Step 7: Install Computer Motherboard

Motherboards are sometimes referred to a 'Mainboards', 'System Boards' or 'Logic Boards' (MAC).

Firstly, in mounting the system board, match the mounting holes in the system board with the holes in the computer case.

The brass or aluminium standoffs that came with your case mounting hardware should be installed in the case to support the mainboard at the appropriate locations.

The installed standoffs should be properly tightened but not over-tightened. (See Diagram A below).

Note: Sometimes it's more convenient to install the processor (CPU) and heat sink assembly on the mainboard before installing it due to space restrictions.
