Werkzeuge

Schritt 1

Orient the iMac face-side down on a table with the bottom edge facing yourself.
Remove the two Phillips screws securing the access door to the bottom grille of your iMac.
The screws are captive in the access door.
Before beginning the repair, unplug the computer and press and hold the power switch for 20-30 seconds, to discharge internal capacitors.

As you remove the screws during these steps, place them on a towel or a piece of cardboard. With a Sharpie label a piece of masking tape with the step number from which they were taken from. Then place the removed screws under the tape.

This ongoing step will aid in you having control on your reassembly without searching for and identifying the size and length all the screws that you are about to remove.

Schritt 2

Remove the access door.

Schritt 3

Remove the three T8 Torx screws securing the front bezel to the rear case along the lower edge of the iMac.

Schritt 4

Turn the computer over.
Use your thumbs to press both RAM arms in past the front bezel for enough clearance to lift it off the rear case.

Schritt 5

While holding the RAM arms in with your thumbs, lift the lower edge of the front bezel enough to clear the rear case.

you might have more luck by gently leveraging the stand up

Schritt 6

Re-orient your iMac so it sits upright on the stand.
Insert a plastic card up into the corner of the air vent slot near 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.
It may be necessary to apply several layers of duct tape to the top of the access card to aid in releasing the latches.
If the bezel refuses to release, try pressing the lower edge back onto the rear case and repeat this opening process.
Alternatively, you can use a strong magnet by holding it to the front top left/right corner of the display. You will hear a snapping sound when the hatch is released.

If it still does not release try pressing in and out (like an accordion) with the card in one hand and the screen bezel in the other until it pops loose.

If your computer has ever been worked on by an authorized Mac repair shop, this step may not be needed. I was able to skip this step after lifting the lower edge of the front bezel. Front bezel lifted off easily.

Schritt 7

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.

My A1145 seems to be attached, somehow, on the top via some silver looking strips. It does not seems to want to come off. Is that the wireless?

Chris Arnold -

NO they are clamps on each of the top inside corners of the outside bezel (frame ) if you use a Heavy Spudger Tool & pry not too hard just slightly between the bezel (side) and the display (side) this should pop each off usually by just popping one or the other sides the second will automatically pop as well.
