    • Before beginning, unplug your iMac and lay it on a soft surface as shown.

    • Stick a suction cup near each of the two top corners of the glass panel.

    • To attach the suction cups we sell, first position the suction cup with the movable handle parallel to the face of the glass panel. While lightly holding the suction cup against the glass, raise the movable handle until it is parallel with the other handle.

    • If your suction cups refuse to stick, try cleaning both the glass panel and the suction cup with a mild solvent.

    • Gently lift the glass panel perpendicular to the face of the LCD enough to clear the steel mounting pins attached along the underside of the top edge of the glass panel.

    • Pull the glass panel away from the lower edge of the iMac and carefully set it aside.

    • During reinstallation, be sure to meticulously clean the inside of the glass panel and the face of the LCD as any dust or fingerprints trapped inside will be annoyingly visible when the machine is turned on.

    • Slightly lift the top edge of the display out of the outer case.

    • Do not lift it too much. There are several cables attaching the display to the logic board. Twisting or pulling the display assembly with the cables attached will damage your iMac.

    • Rotate the display out of the outer case enough to disconnect the LED backlight power cable from the LED driver board.

    • Disconnect the LED backlight power cable by depressing the locking mechanism while pulling the connector away from its socket (toward the bottom edge of the iMac).

    • Grab the plastic pull tab secured to the display data cable lock and rotate it towards upwards.

    • Pull the display data cable straight out of its socket on the logic board.

    • Do not lift up on the display data cable, as its socket is very fragile. Pull the cable parallel to the face of the logic board.

    • Lift the inner edge of the optical drive and maneuver its connector past the GPU frame attached to the logic board.

    • Carefully pull the optical drive off its mounting pins on the right side of the outer case to gain clearance for disconnecting the optical drive cable.

    • Allow the optical drive to hang down as you de-route the optical drive thermal sensor connector from behind the GPU heat sink.

Great How-to, except the how to find the replacement Optical Drive... Can't find the 2428 online anywhere. Any help with the part number before cracking the iMac apart would be greatly appreciated!

Great tutorial. Now if I wish to replace the Superdrive by an SSD (the Superdrive is dead), since the SATA port of the Superdrive is 3Gb/s only, can I keep the Superdrive cable for the SSD but swap it plug to the free SATA III port on the motherboard? Or do I need a new cable?

Thanks

What kind of caddy do I need if I want to put an SSD in there? Is it 9.5mm or 12.7mm? Is any of it non-standard?
