Passo 4

Lift the ear of the fan nearest the RAM up off the standoff secured to the outer case.
Removing the standoff screw is not necessary to remove the fan. You need only raise the fan enough to lift it off the standoff screw.

Remove the following screws securing the antenna plate to the mini:
Two 6.6 mm T8 Torx screws
Two 5.0 mm T8 Torx or 2.0 mm Hex screws (either screwdriver will work)
When putting back together:
It can be difficult to get the hard drive seated correctly such that the antenna plate fits in place correctly. If the screw holes don't line up with those on the hard drive, make sure that the two pins that are in the back of the hard drive are properly seated in the holes at the back of the case, above the housing for the second hard drive.
The antenna attaches directly to the hard drive (red markers), therefore attaching the antenna can move the hard drive around and loosen the connection of the hard drive cable to the logic board.

Passo 9

Slightly lift the antenna plate from the end closest to the RAM.
Carefully pull the antenna plate away from the circular rim of the outer case.
Do not remove the antenna plate yet. It is still attached to the AirPort/ Bluetooth board.

Passo 10

Use the tip of a spudger to carefully pry the antenna connector up from its socket on the AirPort/Bluetooth board.

Remove the following three screws:
One 5.0 mm T8 Torx or 2.0 mm Hex screw (either screwdriver will work)
One 16.2 mm T6 Torx screw
One 26 mm T6 Torx standoff

To remove the logic board, the two cylindrical rods of the Mac mini Logic Board Removal Tool must be inserted into the holes highlighted in red. Inserting instruments into any logic board holes other than the ones highlighted in red may destroy the logic board.
Insert the Mac mini Logic Board Removal Tool into the two holes highlighted in red. Be sure it makes contact with the top side of outer case below the logic board before proceeding.
Carefully pull the tool toward the I/O board. The logic board and I/O board assembly should slightly slide out of the outer case.
Cease prying when the I/O board is visibly separated from the outer case.
Remove the Mac mini Logic Board Removal tool.

Passo 16

Pull the I/O board/logic board assembly out of the outer case enough to access the power connector.
Use your fingers to disconnect the DC-In cable from the logic board.
Pull the power cable connector toward the front side of the mini.

Remove the single 5 mm T6 Torx standoff from the heat sink near the edge of the logic board.

Editar

Passo 21

Remove the following screws securing the heat sink to the logic board:
Four 8.6 mm T8 Torx screws
One 2.6 mm T6 Torx screw
Keep track of the springs held beneath each of the T8 heat sink screws.

Passo 22

Remove the heat sink from the logic board, minding any cables that may get caught.
If the heat sink appears to be stuck to the logic board after removing all screws, it may be helpful to use a spudger to separate the two components.
If you need to mount the heat sink back onto the logic board, we have a thermal paste guide that makes replacing the thermal compound easy.
