  1. iMac Intel 20" EMC 2133 and 2210 CPU Replacement, Access Door: passo 1, immagine 1 di 1
    • Loosen the single Phillips screw in the center of the access door.

    • This screw is captive in the access door.

    • Remove the access door from your iMac.

    isn't it actually pc2-5300s ?

    • The glass panel is fixed onto the front bezel with fourteen magnets around its perimeter.

    • Stick two suction cups to opposing corners of the glass panel.

    • To attach the suction cups we sell, first position the suction cup with the movable handle parallel to the face of the glass panel. While lightly holding the suction cup against the glass, raise the movable handle until it is parallel with the other handle.

    • If your suction cups refuse to stick, try cleaning both the glass panel and the suction cup with a mild solvent such as Windex.

    At this stage and later handling the LCD I found thin cotton gloves helped to reduce smudges

    My GPS unit's car mount suction cup worked nicely here - couldn't find any at the store and didn't want to wait for mail order!

    Two cups would make it easier but one is fine if you place it in the center and are careful to pull the panel straight out.

    Mathew Hendry - Replica

    Why use suction cups when some finger nails will do the job nicely, though a plastic spudger might work too. Start at a top corner. Prize the glass away from the case and leave finger nails in. Move the other hand along the top edge and then with finger spread peel the screen cover away. Be careful not to twist plastic I suppose, but I've had no difficulties.

    damianwise - Replica

    3M Command Strip hooks in opposite corners is another fabulous option when suction cups are not available!

    Adam McCombs - Replica

    Tape works fine, here. Search for a YouTube video for a simple look-see.

    Richard - Replica

    I didn't have any suction cups, but my pencil sharpener (the kind that suctions to the table) worked great. I put it on the middle and lifted straight up.

    Lisa Mac - Replica

    For a quick 'n' dirty alternative "tool" for this step, take a look at IKEA's Stugvik suction hooks: they provide an excellent adjustable grip. Just used it to take apart an EMC2133. Cheers!

    Suction cups usually available at Home Depot or Lowes, in the flooring section. (They're used to handle large ceramic & stone floor tiles.)

    Griff in Fairbanks - Replica

    I can confirm it is fairly easy to pull it up, the heavy duty suction cups were adequate of course, but pretty sure you can do it without heavy duty stuff? Panel is rather light too.

    • Gently pull the glass panel straight up off the iMac.

    • The glass panel has several positioning pins around its perimeter. To avoid shearing these pins off the glass panel, be sure to only pull straight up during removal.

    • Be meticulous about cleaning the LCD and the inside face of the glass panel before reinstallation, as any fingerprints or dust trapped inside will be annoyingly visible when the display is on. Placing the glass flat, inside face down, on a fresh aluminum-foil surface is a good way to keep it clean.

    In order to avoid unnecessary smudges and what not I covered the LCD itself with some plastic wrap while doing the hard drive upgrade. When I reinstalled it all I needed to do was blow off a few dust particles.

    robgendreau - Replica

    While you are at it, it is worth cleaning out dust within the case to help with cooling - particularly around the fans and vents.

    For the screen I used a lens cleaner from my camera bag. These have very fine fibers and won't leave detritus.

    Mathew Hendry - Replica

    Note that the front glass panel is quite light. When reassembling I found it impossible to get the LCD free of dust with the computer lying on its back. I had success with standing the computer up, tilting the LCD down as far as it goes, holding the glass panel upright in front of the computer (about 1 foot away), lightly spraying both the LCD and the back side of the glass panel with compressed air, and then attaching the glass panel (with the computer upright). It took me 5 tries before it was completely clean of dust once the front glass was on.

    axel - Replica

    Although I do not advise it, you can substitute the suction cups with two strips of duct tape along the sides of the glass, with the tape attached to it's self in the middle of the strip

  3. iMac Intel 20" EMC 2133 and 2210 CPU Replacement, Front Bezel: passo 4, immagine 1 di 1
    • Remove the following 12 screws securing the front bezel to the rear case:

    • Eight 13 mm T8 Torx.

    • Four 25 mm T8 Torx.

    On the 24" EMC2134 there are 3 screw sizes: 6x13, 4x20 & 2x30mm, particular note should be made of their location.

    john31 - Replica

    Note for the less experienced.. the case is plastic and the metal coarse thread screws will easily cut a new thread in the hole if you don't line up the screw in the original thread. Do this a few times and the hole will be stripped and the screw no longer tightens.

    TIP:- place the screw in the hole and rotate BACKWARDS/counter clockwise (for RH threads) until you hear/feel it click/drop into the original thread then tighten the screw down. rotate it a couple times to get the feel of things. If there is any significant resistance you probably don't have the original thread.

    This trick also works on the fine metal thread screws and can help avoid cross threading them.


    Richdave - Replica

    On the 24 inch iMac Model A1225 EMC #2134, the two T8 Torx screws in the middle are the longer of the four total bottom 25 mm screws. Just a note for reassembly.

    I think you're missing this step: With the iMac lying on its back screen facing up, grasp the aluminum sides of the bezel and carefully pull it straight up. Then disconnect the microphone cable. Took me a while to figure it out.

    Richard Cacciato - Replica

    I found it helpful to use a few lids from spaghetti sauce jars to hold the different screws. I used a sharpie to mark the inside of the lid w/ location taken from or the step number from directions. Then I placed a small magnet under the lid to hold the screws inside the lid in case I accidentally jostle something on the table. Worked great! You can also use a magnetic knife bar to line up the lids in sequential for the project.

    tom - Replica

    I cut a hardwood block and drew the outline of the the iMac shape with the base as key. I then drew another two lines at 1/2” and 1” all around from the outline. This done I drilled holes for each screw (12 Outer securing the front bezel to the rear case , and 8 Inner screws securing the display panel to the rear case ). That way I don’t lose any or get them mixed up.

    • Place your hands at the top corners of the bezel (to the side) and lift the bezel 2-3cm from the body by working from the top. After this you can also disengage the bottom of the bezel (the memory modules will prevent the bottom of the bezel to detach first). When reassembling, start with the bottom of the bezel.

    • The top of the bezel hosts a microphone attached to the logic board. Gently lift the bezel to not damage the microphone wiring or connector by accidentally pulling the cable.

    • At this point, you can either detach the microphone cable and remove the bezel, or keep the microphone cable attached and rest the bezel on your work surface or the chassis of the Mac.

    • To fully detach the bezel: disconnect the microphone cable connector, removing tape as necessary.

    • To keep it attached, leave the microphone cable attached to the logic board, and place the bezel 'above' the chassis, with the microphone cable forming a hinge.

    • If you keep the microphone attached to the chassis, make sure you don't accidentally damage the microphone or logic board by bumping into the loose bezel.

    I avoided this step by just flipping the housing over and having it lay flat on the table. The tape on mine was on really tight, and I risking ripping the wires out of the connector if I messed with it (I didn't have some really small scissors which might have helped removing it). I would suggest either securing the body of the iMac and the housing to the table you're working on, or somehow securing the housing to the body, so that it doesn't move around accidentally, since it's only hanging on by a very thin wire at that point.

    robgendreau - Replica

    ^^^ This! This tutorial should be amended for this step. Much, much easier and less damage-prone.

    (There really oughta be a step addressing the removal of the bezel as well.)

    cklarson -

    Make sure you do not pull this apart by the wires. Have a firm grasp on the plastic parts. Do not force back together. It only goes back together one way. Also, it is crucial when placing the aluminum bezel back in place that this wire is out of the way. It often gets in the way and is easily damaged.

    Kyle Freeman - Replica

    CAUTION - To disconnect the cable, you'll need to support the bezel while you carefully extract slack microphone cable which is tightly tucked within the iMac. (I didn't have this guide's 'notes on' and missed robgendreau's warning - then inadvertently shifted the bezel and busted my microphone cable in this step.)

    dagnew - Replica

    Don't forget to pull the microphone cord out before you put the panel back on. Otherwise you will have to go back and remove screws to find that microphone cord

    Melvin Hines - Replica

    As robgendreau says, avoid this whole step by opening the bezel and laying it upside down above the iMac, still connected by the mic cord, just carefully. Then replace the battery, suck/blow out your dust, and carefully rotate the front bezel back over the iMac from where you removed it. No cord manipulation or damage at all!

    recmsoj - Replica

    When reassembling the bezel, you should actually gently pull the microphone connector (and cables) through the ~1 inch long slot in the bezel next to the iSight camera, when lowering the top part of the bezel onto the chassis . Then further lower the bezel onto the chassis of the iMac, while making sure there’s no room / play between the bottom of the bezel and the bottom of the body (where the memory slots reside). . This way you’ll avoid damaging the microphone cable. Finally gently push the microphone wires and connector through that sale long slot in the bezel to conceal them inside the bezel.

    • When reassembling the bezel:

    • be sure to tuck the microphone cable and connector into the void next to the camera board.

    • Gently guide the microphone connector and cables through the ±1in long slot at the right of the iSight camera. Once the bezel is properly assembled, gently push the microphone connector and cable into the bezel through that slot.

    • Pull the LCD temperature sensor connector straight up out of its socket on the logic board.

    • If necessary, de-route the LCD temperature sensor cable from behind the logic board.

    • When you remove the LCD, check the routing of the LCD temperature display cable. On reinstalling the display, be sure this cable does not block one of the bottom screws for the front bezel.

    This was the most confusing step, because the video shows MJ just tilting the monitor open, and I had a ribbon cable hooked up to it. Finally figured out that the ribbon cable was connected to the LCD temp sensor cable, and it was neatly tucked under the adjacent fan. Had to pull it pretty hard to get it out from under the fan, and then could tilt the LCD. Instructions are not completely clear about this, only that you may have to reroute the cable around the motherboard.

    d3nn151950 - Replica

    I agree, there is no sign of how to remove the bezel (it took me several minutes to understand it was even the bezel that came off here) in these steps (in all the guides for this model, in fact). On step 4 says remove the LCD screws, and suddenly step 6 shows innards and fans etc - !! - What about showing the bezel being removed here - super confusing and not up to usual ifixit high standards.

    hutchwilco - Replica

    If you rush through the reassembly, it's very easy to miss reconnecting the LCD Temp Display cable. I just did it and one of the fans came on full-speed and stayed there through a new macOS install. Did a Google search and found mention of this symptom. At first I was thinking I switched one or more of the inverter cables but this guide shows that this is not a problem. Once I reviewed this step, the problem was obvious as was the solution. Thanks again, iFixit, for saving my nappy behind.

    barryjaylevine - Replica

    I can speak from experience, this cable’s a pain. It came out of where I tucked it and snuck behind one of the bottom screws, which pierced it during reassembly, afterward it would not boot properly. It’ll boot without the cable plugged in, but the fan runs near max. I’m glad it can at least be used while I wait for the replacement cable to ship. What a weird (lazy) design choice from Apple.

    Ian Sprenkle - Replica

    In case the iMac hasn’t been opened for years (typical situation), then you may want to first carefully and prudently remove the piled up dust with a vacuum cleaner and a soft brush. Definitely not with a can of compressed air, as then you’ll spill the debris everywhere (and on the display). Otherwise you won’t be able to get hold of the right cable, connector or screw. In addition, it will help increase the air flow hence reduce heat (and allow the fans to operate at a lower speed).

    Olivier Biot - Replica

    hi could some one help me with this cable replacing as it has been damaged i mean i would like to know if i could repair the wire or simply replace it and also what type of wire i would need and how could i find one please i m new thanks

    • Remove the two 5.3 mm T6 Torx screws securing the data display cable to the logic board.

    My Torx 6 driver purchased from ifixit didn't fit the screws well and potentially would strip them. Had to purchase a better driver to fit better in order to loosen these screws.

    kakisback - Replica

    reinstalling these screws requires extra care to be sure you don't drop it and loose it under any of the other components.

    kakisback - Replica

    Make sure not to drop the screws.

    ulan - Replica

    Removing these screws was the most difficult part of the whole job. They were tight and felt as if the heads were about to chew up. I had to press really hard and jerk the screwdriver counter clockwise to loosen them. Despite others' warnings, I managed to drop a screw when reinserting.

    kevinp - Replica

    The only tool I needed to buy was the T6 Star Bit - the first auto store I went to had it. These screws are tiny so you have to be careful not to drop them!

    James Miles - Replica

    When reinstalling these tiny screws, consider placing the iMac upright. That way when you (inevitably) drop these tiny screws, you don't lose them in the guts of the computer where they are likely to fall into a fan.

    stown1211 - Replica

    Yes, this step is very difficult. I finally used a magnet to magnetize the torx driver, and that helped immensely...however, that was AFTER I lost the right one inside the computer. You really only need one screw to reattach the monitor connector, however.

    d3nn151950 - Replica

    Argh! I dropped my right screw into the bowels of the iMac. I can't find it anywhere and am loath to leave it rattling around as well as to tear down the machine any further.

    steven macfarlane - Replica

    Well, I followed the instructions for right-speaker removal and optical drive fan removal and still couldn't find the right screw. I couldn't hear it rattle either so figured it was wedged somewhere. Using an inspection mirror and flashlight, I finally found it. It had fallen down and wedged between the PCB and the plastic housing (below the ports). I was able to slide it toward the right until it came to the void left by the right speaker where it fell out into my hand.

    steven macfarlane -

    It's true, these were super tight. I only had a T5 which worked on the first screw, but the second wouldn't budge. Ended up filing the tip off the T5 bit - presto! - instant T6.

    marcintosh - Replica

    I Think the real screw size is 3.5 mm T6 Torx, not 5.3 mm

    raul - Replica

    Dropped those little bastards like 2-3 times into the deeps of my iMac. The right one is really tricky. If you drop it: better get yourself very thin tweezers and gently shake your mac. :(

    Popelnase - Replica

    Note that just below where you are working is the PRAM battery. If you have never replaced this, now is a good time so you won't have to open the machine up again in the near future. The battery is a CR2032.

    mattgauntt - Replica

    Taking all the warnings into account about losing these tiny screws, during removal and replacement I held onto the screws tightly with a very fine needle nose tweezer. Fortunately I managed not to lose them either out or in. I highly recommend using a small gripper during this step.

    recmsoj - Replica

    While you have the case open this would be a good time to replace the PRAM battery and carefully clean the fan and interior of the case with Q-tips / compressed air.

    John Fisk - Replica

    These screws are Torx 7 - at least that was what

    I used on them and got a prefect tight fit ... .

    pdienstm - Replica

    If you do manage to lose one of these screws, will the cable still be held in properly if you reinstall it with only one?

    Peter Wood - Replica

    Advice / 2 cents : Unscrew/screw with the iMac vertical/propped up and a magnetized screwdriver. Should be no issue. If it falls, it will fall on your desk, not behind stuff on the back of the iMac. You could even put iFixit magnetized mat underneath for added safety :)

    • Remove the eight 12 mm T8 Torx screws securing the display panel to the rear case.

    • Lift the display panel from its left edge and rotate it toward the right edge of the iMac.

    I was able to disconnect the two connectors to the front easily. With those off, I just rotated the LCD out of the way to expose the hard drive. Again, make sure it's stabilized if you do this so that when you yank on something else you don't send it flying.

    robgendreau - Replica

    I did a HD replacement on my 24 inch iMac. It's basically the same, but it does not have disconnectable invertercables. Instead, there's just one cable that's can't be disconnected. It sits too tight to rotate the display to the degree that you can lean it against something, so the only way to get the job done was to call in an extra set of hands to hold the display while I took out the hard drive.

    Marijn - Replica

    On the 2134 model, I found that the LCD must be lifted from the RIGHT (not the left as per the 2133 guide) - the connector wires are covered in nylon housing and it's way easier just having someone hold the LCD vertical whilst you replace the HDD, unless you have small fingers and feel like disconnecting completely ...

    • With the display panel still lifted, disconnect the four inverter cables.

    • During reinstallation, place the four inverter cable connectors in voids between components attached to the rear panel so the display panel will sit flush.

    • During reassembly, the order of the inverter cables is interchangeable within each socket.

    • If you are replacing a hard drive and have an extra set of hands, it is possible to reach in and remove the drive without disconnecting anything but the LCD temp and display connector in the previous step with the LCD in its propped position.

    Make sure to not squeeze the inverter-cables between the superdrive and the display when putting the display back on !

    epzzky - Replica

    This was the only step different for my 2134 - it is just one cable that connects to the monitor - disconnect the monitor end rather than the motherboard side.

    Jim Laredo - Replica

    There is no need to discnnect the inverter cables if display is positioned against a wall or something of the sort. Make sure it doesn't tumble over !!!

    info5825 - Replica

    For 24" iMacs, a single power cable is attached on the left side of the screen. To remove the cable, lift the screen from the right side and rotate it to the left. Remove the black plastic protector on the back of the screen and disconnect the cable.

    Matt Stichnoth - Replica

    Make sure you squeeze the two ends of the inverter cable together firmly - if not you will get yellow areas on your screen. One of my cables had not quite been clicked together, and I had to unscrew everything all over again.

    Philip - Replica

    So does it matter which ones are connected to which?

    That is, at each end there are two connectors (one pink/black the other light blue/dark blue on the "male" side). The "female side appear identical. Does it matter if the pink/black "male" one is connected to the wrong "female" one?

    Mark Gibson - Replica

    Mark, did you ever get an answer about the connectors?

    Mike -

    Agreed this is an unspecified issue and i'm surprised it's not covered? Did everyone else just guess?

    kainatticus -

    Yes, mark each female end in a way that distinguishes itself from the other. I put “P” on the harnesses with the pink wires and “B” on the harnesses with the blue wires.

    steven -

    So let’s say hypothetically I didn’t label them as I failed to notice that they were identical before disconnection. What should I do to resolve this issue?

    Christian Moore -

    Managed to avoid this step just lifting the lcd panel and holding it with my... head ;)

    Antonio Bernardini - Replica

    Yes, I agree. If you just prop the panel up on the left (carefully!) with your head, or as I used a box, or get a friend to hold it up, this step can be bypassed. It is a tight squeeze inside to work with getting the HD in and out but its totally do-able. If using an SSD, which of course you should, you can just tape it down inside, as they weigh almost nothing.

    Andrey - Replica

    I tagged the inverter cables with different color sharpies so as to get them connected back the way they were.

    Macrepair SF - Replica

    Step 9…. before I took those tiny screws out for the data display cable on the logic board, I put the tip of the torx tool on a magnet (magnets on the front cover worked fine) for a few minutes. this magnetizes the screws so you are less likely to drop them when you go to put them back in.

    dkkd - Replica

    I replaced the internal hard drive. worked fine. putting everything back together, the CD drive wont insert or eject discs when I tighten the screws on the right side that holds the display in place, or when I put the cover back on. CDs work fine if I leave the screws loose and/or leave the cover off. cant figure out why, i never touched the CD drive at all…

    anyone else have this issue after opening the unit up, and how did u fix it?

    dkkd - Replica

    This happened to me and I found that a cable that had been wrapped around the side of the DVD drive had slid over top of it while I had it open. When I closed it all up, the pressure of the cable against the surface of the DVD drive was enough to impact it. I reopened the machine and pushed the cable back around the side of the DVD drive and it worked fine.

    John Moltz - Replica

    The ‘locking tab’ faces the dot. I placed a label on main body side of the lcd connector with a P =Pink and B =Blue. This way I know to place the connector with the pink on the marked P and blue on the marked B.

    egecko - Replica

    I went with the option of not detaching the screen. I have horror stories around inverters, mostly on notebooks, but still, don’t approach/touch if you don’t have to.

    Ask your wife/somebody to hold the screen while you go through the steps below, without detaching the cables in step 11. It is a couple minute to step 18 and having the drive out.

    • Remove the single 28 mm T10 Torx screw securing the left speaker to the rear case.

    • Lift the left speaker up and out of the rear case. Don't try to slide the speaker out, since there is a plastic mounting pin under the top end of the speaker housing that holds it in place.

    I found it impossible to lift the speaker out without breaking the plastic mounting pin. All I can say is don't worry about it if it happens. When I put it back and tightened the screw, it seemed solidly in place.

    mattgauntt - Replica

    just completed this step without breaking positioning pin. it appears a small amount of clear liquid adhesive was used to secure this top pin. i slid my hand underneath the speaker and rear case and used my other hand to guide the speaker straight up and with considerable force pulled the housing free of positioning pin without damage.

    • The SATA connector on most iMacs tends to stick in its socket on the logic board. If you are having trouble disconnecting the SATA cable, insert a metal spudger or any other thin tool into the gap between the SATA connector and its socket and twist the spudger's shaft to safely separate the two pieces.

    It is necessary to remove the stuck on plastic cover that covers the RAM sockets in order to remove the speaker and SATA cables.

    Care is needed because it is easy to snap the plastic which has probably aged by the time dismantling takes place!

    • Lift the microphone cable connector straight up out of its socket on the audio board.

    • During reinstallation, ensure that the mic cable runs between the ODD fan and the board support. If the cable runs on the wrong side of the support, the cable will be too short to plug in.

    TIP for re installation..I had the mic cable around the left side board support when I installed the board so it was too short and had to pull the board a out again! Make sure the mic cable runs between the ODD fan and the board support.

    • Remove the following 13 screws securing the logic board to the rear case:

    • Six 7.2 mm coarse-thread T10 Torx.

    • Two 6.8 mm T8 Torx. When reinstalling these two screws, don't overtighten them, as the plastic tabs they hold down are thin and brittle, and can crack.

    • Three 7 mm fine-thread T10 Torx.

    • Two 24 mm T10 Torx.

    The 2133 only has 1x 24mm T10 Torx

    • Lift the logic board out of the rear case, minding any cables that may get caught.

    • If the front edge of the logic board, under the RAM sockets, won't pull up, it's sticking on the three plastic mounting pins in the rear housing under this edge. Use a spudger under the front edge of the RAM sockets to gently push up on this edge until it clears these mounting pins.

    Than you for all expirt information .

    Please, one question?

    After disassemble my IMAC for cleaning cooling system then restored all part and cable.. found that audio not working . I can hear any sound . W I can do?

    • Disconnect the heat sink temperature sensor connector by pulling it straight up from its socket on the logic board.

    By the time I got to this step, this picture didn't resemble anything I see in my 20" early-2008 iMac. I don't know if you forgot the step about removing the fan, but the heat sink isn't visible until you do. Even then, there's no temperature sensor where your illustration indicates there is.

    There's definitely a skipped step here, and there may be some difference between the board you're showing here and the board in the early-2008 iMac. From what I can tell, it's both.

    Newbies, proceed with caution.

    jessedouglas - Replica

    Well, I figured it out. The view shown in this step is from the underside of the logic board, once it's already been removed from the iMac.

    Newbies beware: there are several crucial missing steps in this guide.

As a few others have pointed out, this guide skips over several steps. Basically, start with the logic board replacement guide and when you get to the end of that, start with step 19 in this guide. Then reverse to 19 and then reverse the logic board guide.

Does it require a new CPU socket from the original Imac EMC 2133?

Break Boy Dark AKA MOKKAMANN - Replica

Break Boy Dark AKA MOKKAMANN, what do you mean? In this guide you replace just the CPU of these two iMac models (EMC 2133 and 2210) without touching the socket, that remains on the board.

Replaced my CPU and got into trouble: My iMac won’t boot. When turning it on, three LEDs light up, but not #4. The LCD is connected though. I even had a different LCD connected, same story. Put the old CPU back in, same story. What could be wrong?

i had the same prob. i can’t understand why, but when i unplugged the cd drive, everything was repaired! just take a try… good luck!

A very good description of the processor replacement. This is my first iMac processor replacement and after all - everything works great :-)

Thank you very much :-D

I successfully completed this guide to replace termal paste on the CPU, since this computer has never received service since 2008… Old paste was not terribly dry but undoubtedly needed replacement. This is the second time I’ve opened my old iMac, it was not that hard, definitively the comments were essential for some steps!

Great to save my iMac for some 10 more years, my children use it for fun and school daily and is (still) a very nice computer.

Most times when I take something apart, when I put it back together again I’ve missed something, or something doesn’t work or what have you. This time with this guide, other than lightly trapping the camera wire under the logic board (luckily before I’d plugged that many things back in I noticed; good order to the guide) everything went back together smoothly so far the iMac feels a lot snappier. The SSD hasn’t arrived for it yet but when it does, I think it’ll be good for several more years of quality computing.

I am really concerned about CPU upgrade for my A1224/EMC2133 iMac 20'‘. Here you show one with 800Mhz fsb (one of T7xx family) and link to the page iMac Intel 20" EMC 2133 CPU with E8135 1066MHz fsb CPU as suggested replacement. Thus my question - will swapping T7xxx for E8xxx work ever? Under what conditions? Or I’d better swap T7xxx with 800 fsb for T9300 with 800 fsb in order to get machine running?

Dmitry Tarasov - Replica

absolutely great - clear and precise

my only comment would be to include the steps to dismantle all the fans and clean then - which i sort of figured out lol

and to re-paste the graphics heatsink as well - mine was CRUSTY and the radiators had more dead human skin cells in them than i care to mention

but what a great guide - i would also add - when you do disassembly - label all your cords and label all your screws - i just wrapped them in masking tape with what they were and put them into containers labelled - bezel - screen - logic board etc
