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. Or use two cards for the additional thickness.
If the bezel refuses to release, try lifting the lower edge of the front bezel slightly away from the rear case (detailed in the next few steps) and repeat the latch release process.

Paso 4

Lay your iMac stand-side down on a flat surface.
To lift the front bezel off the iMac, simultaneously:
Use your thumbs to press in the RAM arms and hold the iMac down.
Use your index fingers to pull the small bridge of material on the front bezel toward yourself.
Pull the front bezel up with your index fingers.
Once the small bridge of material has cleared the RAM arms, lift the front bezel by its lower edge just enough to clear the bottom edge of the rear case.

Paso 5

Lift the front bezel off the rear case and rotate it away from the bottom edge of the iMac, minding the camera and microphone cables still attached to its upper edge.

Editar

Paso 6

If necessary, remove the strip of tape covering the microphone cable connector.
The microphone connector is located near the inside of top edge of your iMac.

Editar

Paso 7

Installing iMac Intel 20" EMC 2105 and 2118 Dual Hard Drive: paso 7, imagen 3 de 3

Disconnect the microphone cable.
Disconnect the camera cable by pulling its connector away from the socket on the camera board.
The camera cable connector and socket are delicate and easily bent. Remove with caution.

Paso 8 Lower EMI Shield

Installing iMac Intel 20" EMC 2105 and 2118 Dual Hard Drive, Lower EMI Shield: paso 8, imagen 1 de 1

Peel up the lower EMI shield from the rear case.
It is only necessary to peel the shield up from three sides. Leave it attached to the display.
If you happen to rip the EMI shield, use a piece of foil tape to cover the tear.

Editar

Paso 9

Tape the EMI shield to the face of the display to keep it out of the way.

Remove the two 5 mm T6 Torx screws securing the display data cable connector to the logic board.
Pull the display data cable connector up off the logic board by its black pull tab.

Editar

Paso 11

Peel back the EMI tape from the two vertical edges of the display.
During reassembly, it is helpful to use several small strips of tape to hold the EMI shielding along the left and right edges of the display footprint out of the way before lowering the display into the rear case of your iMac.

Editar

Paso 12

Allow the lower EMI shield to hang down from the display.
Remove the four 7.5 mm T10 Torx screws securing the display to the rear case.
The screws are recessed, so a thin magnetic screwdriver aids in removal. Most bit drivers are too short to reach these screws.

Editar

Paso 13

Lift the lower edge of the display and rotate it toward the top edge of your iMac.
Do not lift it too much, as the inverter cables are still attached.

Editar

Paso 14

Disconnect both inverter cables from the inverter board.
These connectors are seated very tightly in their sockets. It is helpful to use your fingernails or the tip of a spudger to push the ears on either side of the connectors to dislodge them from their sockets. A small pair of hemostats helps a lot.

Editar

Paso 15

Disconnect the two inverter cables at the top edge of the inverter using the method explained in the previous step.

Editar

Paso 16

Rotate the display until it is nearly perpendicular to the rear case and lift it up to peel it off the EMI shield stuck to its top edge.

Paso 17 Optical Drive

Installing iMac Intel 20" EMC 2105 and 2118 Dual Hard Drive, Optical Drive: paso 17, imagen 1 de 1

Disconnect the optical drive thermal sensor cable by pulling its connector away from the socket on the logic board.
Pull the connector parallel to the face of the logic board.

Editar

Paso 18

Remove the two 3.6mm T6 Torx screws securing the optical drive ribbon cable connector to the logic board.

Editar

Paso 19

Use the flat end of a spudger to pry the optical drive ribbon cable connector up off the logic board.
The connector is most easily removed when prying from the top or bottom of the connector.
Bend the optical drive ribbon cable back away from the logic board.
Be very careful when moving the optical drive ribbon cable as it is delicate and easily ripped.

Paso 20

Apple's "engineers" didn't learn much about deflection and material stiffness when they went to "college", so this optical drive is particularly difficult to remove because the bracket flexes too much. The next few steps require some patience and a good amount of force.
Insert the flat end of a spudger into the gap between the optical drive and its bracket until it contacts the chassis.
Grab the spudger as close to the surface of the optical drive as you can, then depress the release tab with your thumb while pulling toward yourself.
The wedge shape of the spudger may cause it to slip out of the gap toward yourself. Be sure to press the spudger in toward the rear case while squeezing the release tab.

Editar

Paso 21

Remove the two 6mm T10 Torx screws from the side of the optical drive.
It's a good idea to lay your iMac flat on a table before removing these screws to avoid them falling behind the logic board.

Editar

Paso 22

Reach behind the chassis and use your finger to unclip the lower optical drive tab from the chassis.

Editar

Paso 23

Maneuver the optical drive out of the rear case, minding the two plastic pins molded into the rear case near the open end of the optical drive that can break off.

Paso 30

Use the tip of a spudger to push the two optical drive bracket tabs out of their slots in the top of the optical drive.

Editar

Paso 31

Using the tip of a spudger, press the optical drive bracket tab out of its slot on the side of the optical drive.

Editar

Paso 32

Use the tip of a spudger to press the optical drive bracket tabs out of the slots in the top of the optical drive.

Editar

Paso 33

Pull the optical drive bracket toward the open end of the optical drive to free it from the optical drive.

Editar

Paso 34

Use the flat end of a spudger to pry the optical drive thermal sensor off the adhesive securing it to the optical drive.
Don't forget to transfer this to your new drive.
