It's finally time to remove the motherboard!

We'll start by releasing the I/O port bracket on the back of the computer.

This bracket is under pressure and will fly across the room if it isn't held down. (That may be why it's called a "Flying Serial".)

Six support pegs are now the only thing holding the motherboard in place.

Slide the board towards the back of the computer and lift up once the pegs are free.
