The ins and outs of replacing your IR board.
-
Loosen the two Phillips screws securing the access door to your iMac.
-
Remove the access door from your iMac.
-
Remove the three T8 Torx screws securing the front bezel to the rear panel.
-
Use your thumbs to press both RAM arms in past the front bezel for enough clearance to lift it off the rear case.
-
While holding the RAM arms in with your thumbs, lift the lower edge of the front bezel enough to clear the rear case.
-
Insert a plastic card up into the corner of the air vent slot at the top of the rear case.
-
Push the card toward the top of the iMac to release the front bezel latch.
-
Pull the front bezel away from the rear case.
-
Repeat this process for the other side of the front bezel.
Using a strongish magnet will grab and release the latches.

Are you sure it's safe to do this? How close is the hard drive, won't magnets interfere with it?
It's almost certainly fine. Modern hard drives are very resistant to magnetic fields.

Lay your iMac stand-side down on a table.
-
Lift the front bezel from its lower edge and rotate it away from the rest of your iMac, minding the RAM arms that may get caught.
-
Lay the front bezel above the rest of the iMac.
-
If necessary, remove the piece of kapton tape wrapped around the microphone and camera cables.

Disconnect both the camera and microphone cables.

Peel back the aluminum EMI shield up off the lower three edges of the rear case.
-
Remove the single T6 Torx screw securing the IR board bracket to the logic board.
-
Pull the IR Board cable connector straight away from its socket on the IR board.
