Loosen the three Phillips screws securing the access door to the bottom edge of your iMac.

These screws will remain captive in the access door.

Remove the access door from your iMac.

During reassembly, fasten the access door loosely and align it with the pocket cut into the outer case of the iMac before fully tightening the screws.

Use your fingers or the tip of a spudger to slide the black plastic RAM tray pull tab out of the RAM slot.

Pull the black plastic tab away from the iMac to eject the RAM chip from its socket.

• The RAM modules are firmly seated and may require a fair amount of force to remove.

Use your fingers to slide the RAM chip out of its socket.

If necessary, repeat this process for the other RAM module(s).

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 (as highlighted in the first and second pictures).

While lightly holding the suction cup against the glass, raise the movable handle until it is parallel with the other handle (as highlighted by the third picture).

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.

Remove the eight T10 Torx screws securing the LCD to the outer case.

Carefully lay the iMac stand-side down on a flat surface.

Due to tight tolerances, you will have to use a thin hooked tool to lift the display out of the outer case. As seen in the first picture, we made one out of a bent paperclip.

• Alternatively, our Dual Hard Drive Kit includes a pair of tweezers with an angled tip that are great for this task.

Use a thin hooked tool to lift one side of the top edge of the display by its steel outer frame.

After lifting the top edge of the display on one side, hold it out of the outer case while you use a hooked tool to lift the other side.

Raise and hold the display high enough to access the cables.

Do not lift the top edge of the display out of the outer case too far, as several short ribbon cables still connect the two components.

Disconnect the vertical sync cable in the upper left corner of the screen. Use the tip of a spudger to push on the connector's side tabs.
