    • Lay your iMac stand-side down on a flat surface.

    • To lift the front bezel off the iMac, simultaneously:

      • Use your thumbs to press in the RAM arms and hold the iMac down.

      • Use your index fingers to pull the small bridge of material on the front bezel toward yourself.

      • Pull the front bezel up with your index fingers.

    • Once the small bridge of material has cleared the RAM arms, lift the front bezel by its lower edge just enough to clear the bottom edge of the rear case.

    My iMac did not have the "small bridge of material" mentioned, however the bezel just lifted off easily.

    • Lift the front bezel off the rear case and rotate it away from the bottom edge of the iMac, minding the camera and microphone cables still attached to its upper edge.

    • The third picture shows the top front bezel brackets and their slots cut into the top edge of the iMac's rear case.

    • Do not completely remove the front bezel, as it is still attached by the camera/microphone cables.

    • If necessary, remove the strip of tape covering the microphone cable connector.

    • The microphone connector is located near the inside of top edge of your iMac.

    • Disconnect the microphone cable.

    • Disconnect the camera cable by pulling its connector away from the socket on the camera board.

    • The camera cable connector and socket are delicate and easily bent. Remove with caution.

    I found it easier not to remove the cables connecting camera and microphone, but rather to lean the plastic frame agains a pile of books so that it could rest almost vertical avoiding the need to disconnect those two sensitive cables.

    I agree that for a simple, quick battery change, don't risk damaging those delicate wires. Ignore Step 6 and instead of disconnecting the mic and camera wires, keep them in place and just have a friend hold the plastic frame up while you change the battery, or prop it up as mentioned by Stefano C above.

    Make sure you double check the new logic board for the presence of the GPU assembly before installing. I stupidly installed a new board without moving the GPU from the old one first. So i guess you can say this guide worked for me twice. :)

The guide does not state you need a T6 until you get to the part where you need to remove the display. Please fix that.

Repair worked like a dream - took a couple of hours tops. Thanks!
