In the photo for Step 28, the power button cable connector is placed around the power board screw hole on the top left of the power board.
However, on the iMac I upgraded, the power button cable connector was “fed” through the power power screw hole on the top left of the power board. The cable was too short to run around and below the hole.
Hence, I had to ensure the cable was “fed” through the hole during re-assembly and the screw carefully screwed back through the hole.
I guess every iMac is assembly just a bit differently, just to make repairs that much more fun.
The photo in Step 51 shows the right speaker missing, however there is no step prior for removing the right speaker.
Hence, refer to this other guide to remove the right speaker *before* Step 51.

I worked through the disassembly steps and successfully replaced the 5400 rpm spindle drive with an SSD drive and the 2 x 4 GB RAM modules with 2 x 8 Gb RAM modules.
An important step/note is missing at the start of the guide and the last step - you must purchase replacement adhesive strips to re-attach the screen to the chasis, as the existing strips are useless after being cut.
Hence, make sure you have a set of replacement adhesive strips ready *before* opening the iMac.

i found the logic board kept snagging on the USB connectors poking through the exterior case. Wiggle the logic gently to extract..
i found it helpful to use the flat end of the spudger under the cable near the connector and gently wiggle the spudger until the cable was disconnected.
