Power down your Mac mini, disconnect all of the cables, and flip it over.
-
Insert the Jimmy into the crack between the aluminum top housing and the plastic lower housing.
-
The Jimmy should reach a stop about 3/8" down.

We will first remove the AirPort antenna, located in the lower left corner of this picture.

Grab the Bluetooth antenna nearest the port side of the computer by the edges of the board and pull it straight up off the internal frame.
On mine, at least, a considerable amount of force was required to get the bluetooth antennas up off the posts. In fact, I ended up pulling so hard one one of them that when it suddenly came up, I broke the antenna cable. Be careful!
They do need a fair bit of force. Best way for me was first finger and thumb underneath, either side of the post; and first finger of the other hand on top to prevent it "jumping". Then just move up in one smooth motion.

Did you repair the antenna or just let it go? I broke my antenna too, and I can't tell if it's a 2-conductor coaxial cable or a single conductor that I could resolder.
Note on re-assembly - there is a "pin" formed from the top of the internal frame which needs to go through the corresponding hole in the antenna assembly. Although the antenna will clip down without it being exactly in place, the antenna will not be "sprung" and will probably foul the cover when it is replaced, probably causing damage.
As you almost certainly wouldn't notice this as you replace the cover, do check that this "pin" is aligned and that the antenna is floating on the spring, before replacing the cover.
I realized, that it made it easier when I grab and squeeze just a little on the spiral thing under the antenna while lifting it up.
A more controlled way of remove the bluetooth antennae: lever them gently off. The closer you are to the centre pin, the more force you will exert there, instead of wasting it bending up the board. You already have the tools - the putty knife & the spudger.
Put the putty knife gently under the board on the side of your non-dominant hand, and then the spudger under the board on the side of your dominant hand. Gently lift the handle of the putty knife and apply constant pressure. Then gently push and wriggle the spudger under the other side with your dominant hand and push constantly forward. The further you push forward, the more upward force you will apply.The antenna will pop up before you get the spudger all the way under, and it will only rise a few mm when it does.
Be aware of cable and Bluetooth antenna board upon reinstall. I attempted to reinstall the board as it faced the incorrect direction, and the cable was improperly positioned. The result? Upon snapping the board in, the cable got caught and portion of it was shorn off near the solder. So, be aware of the board and cable positioning on reinstall.
From what I've read elsewhere- the "spiral thing" under the antenna is a plastic clip that
needs to be pinched together with fingertips,to release the antenna from its post.
This should also be done when replacing it, to ensure the antenna will clear the case.
Seems like this detail was skipped in other instructions here.

Simultaneously pull the tabs on each side of the RAM chip away from the center of the chip. These tabs lock the chip in place and releasing them will cause the chip to "pop" up.
-
Pull the RAM chip directly out from its connector.

Well done! Easy to follow and thorough! Took me 10 minutes start to finish!
You probably need to install Mac Mini EFI firmware update 1.2:
Wife has the Late 2009 Macmini (MM) originally with 2GB. We upgraded to 4GB a couple of years ago, and it has been running very slow with Yosemite (10.10.5) for far too long.
Ordered the 8GB upgrade kit and set for 2 day delivery. Bummer it came in 1 day via UPS. Thanks for the surprise iFixit. The tools were unnecessary for me (as I have most), but they are totally outstanding and the real deal. So I decided to use them all. ;)
The upgrade took about 15 min (even for this experienced Mac repair guy). Fired it up and the MM recognized all 8GB. It doesn’t scream, however, it is probably 2-3 times faster and can handle the amazing multi-takser that is my wife; 16 Safari pages, Mac Mail, Calendar, and 7 other apps open at all the same dang time. Thanks iFixit for the absolute best in repair universe parts, service, tech commitment, and guides.
It worked!!! Love it!!! The websites installation guide was very easy to understand. However, the small screwdriver that was shipped with the kit didn’t fit the screws for step-12, almost stripping the screws. luckily, I had another small screwdriver (for glasses) that worked.
Thank you ifixit!!! Totally worth it.
Did it in about 5 Min. The Old Macs are great to work with. One Thing i can recommend is a longer bit for your Skrewdriver.
It worked!!! Got a Mac Mini Late 2009 and the Apple Website told me it just supports 4 GB. Just built in 2 x 4GB RAM and it’ running… Thanks for the great how to guide. I love my Mako Driver Kit from iFixit, best screwdriver kit!!!
Worked, very helpful. The one thing I needed that was different was a prying tool to open the case. The Jimmy was too flimsy on its own. Had to use the Jimmy on one and the painter's tool on the other. The Jimmy by itself was to flimsy, and instead of the case opening, the Jimmy would bend. Note that you need to be careful with this; I ended up bending one of the pins that hold the chassis in place.
