Step 4: Remove the logic board from the aluminum body

With the unit oriented with the ports facing you, disconnect the small cable in the far back (indicator light I believe?). This connector goes straight up. Next, unplug the big power connector on the right hand side. If there is not enough room to disconnect it fully at this moment, do not worry as you will be able to do so once you begin sliding out the logic board.

To remove the logic board, unscrew the two (2) T10 (or T9) screws in the upper middle of the logic board. With those removed, you can use a Mac Mini Logic Board removal tool or be ghetto like me and use two small screwdrivers to lever the logic board out of the casing. Once you get it moving a bit, you can also gently push the heatsink to push out the logic board.

If you didn’t fully unplug the power cable, do so now.

Pull the logic board out of the case and place the case aside.
