    • Flip your iMac over and lay it 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.

    • 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.

    • 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.

    • We have found it helpful to tape the EMI shield against the display to keep it out of the way.

    • Peel back the aluminum 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.

    • Allow the EMI shield to hang down from the display.

    • Remove the four 8 mm with 2 mm thick head coarse-thread T10 Torx screws securing the display to the rear case.

    • These screws are recessed, so a thin screwdriver such as this is essential for removal. Bit drivers tend to be too short for this application.

    • It is strongly recommended to use a magnetized screwdriver so the screws won't fall into the iMac.

    • Lift the display from its lower edge and pull it toward yourself to peel off the EMI shield attached to its top edge.

    • A hard drive thermal sensor may be present on some models. If your logic board is missing the hard drive thermal sensor socket highlighted in red in the first picture, skip this step.

    • Pull the hard drive thermal sensor connector away from its socket on the logic board.

    • Pull this connector parallel to the face of the logic board toward the top edge of the iMac.

    • Use a spudger to pry the thermal sensor and adhesive off the hard drive and install it in the same location on the replacement drive.

    • Press the hard drive bracket down to free it from the rear case, then rotate the top of the drive toward yourself.

    • Pressing the top of the hard drive bracket down to release it from the rear case requires a substantial amount of force, so we recommend laying your iMac stand-side down on a table to avoid knocking it over.

    • If you have trouble releasing the hard drive bracket, it can be removed from the hard drive, by removing the two T8 or T10 Torx screws securing the bracket to the drive.

    • The next few steps bring your hands close to the exposed face of the power supply. Do not touch the face of the power supply to avoid a high voltage shock from the many large capacitors attached to the board.

    • Unplug the power supply cable bundle from the logic board by simultaneously depressing the locking mechanism (toward yourself) with a spudger and pulling the connector away from its socket.

    • The locking mechanism faces the rear case.

It was quite easy, but a little fiddly. I didn't need to remove the hardrive to replace the power supply.

The PSU in the 17” is smaller than shown and has the DC - DC convertor above it.

Marcus Evans - Antwoord

DC - DC convertor is above the psu in the 17” model and the psu is half the size than that shown.
