Lay the iMac display-side down on a flat surface.
Loosen the three Phillips screws securing the rear panel to the iMac.
These screws are captive in the iMac. The center screw will stop turning after about 3.5 turns and the outer screws will stop turning after about 5.5 turns. Do not try to remove these screws from your iMac.
The following action is optional. If you skip this step, be very careful not to strain the thermal sensor cable as you disconnect the hard drive cables and transfer this bracket to your new hard drive.
Lift the hard drive slightly and disconnect the hard drive thermal sensor connector.
Remove the two 6 mm T10 Torx screws from the hard drive and remove the hard drive bracket.
The hard drive bracket with the thermal sensor board is attached to the SATA connector side of the hard drive.
If you are installing a new hard drive, we have an OS X install guide to get you up and running.
