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.
-
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.

Something I don't get…
I'm investigating on my mid2007 iMac power problems and I don't get the same results of voltage as in this article. In my case, number 9 is at around 12V and number 8 is at 0V.
Is my PSU really faulty or there might be some other PSU models?
I've got the same results as you. Wondering if we have the wrong ps model, despite being what iFixit recommends and sells. Very odd.
i have the same issue. Do we have the wrong power supply or the wrong voltage chart?
Have also the same, maybe the table here is wrong. What kind of problems does your mac have?
