Problem re-assembling front cover clips on an iMac 5,1
Replacing the Front Bezel (17-inch)


Position the front bezel near the top edge of the unit and connect the two camera board connectors.
Make sure the black EMI shielding along the top of the LCD panel is not in the way of the locking mechanisms when you lower the front bezel onto the computer. Use a black stick to press (re-stick) the EMI shielding along the top of the panel.


Wrap the cables with kapton tape then tuck the cables neatly into the channel on the rear housing.


Make sure the memory ejector levers are in the closed position (as shown) before lowering the front bezel over the ejectors.


Continue to lower the font bezel down and press the top corners of the front bezel to connect the latches. Note: Check that the latches are connected by lifting the front bezel at each corner.
Replace the four bezel screws along the bottom of the computer.
Replace the access door and tighten the two captive screws.
Install any removed DIMMS after the unit is fully assembled. Important: Memory DIMMs must be installed by hand. Do not use the memory ejector levers to install memory.
