Sorry, I haven’t more details of the breakdown. The most difficult part was to clean up the power supply board and to saw parts of the plastic chassis to fit the MacMini inside. The parts I kept from the original machine are the chassis, the power supply board and the framework that sustained the original screen.
I have added some pictures of the fan.
Hi James, the fan is 80x80x25, 2-wire and can be removed from the metal housing.
