Upgrade your original 1984 Macintosh to run OS X Snow Leopard.

Step 5Mounting the internals - Part 1, The Motherboard.

Mounting the internals - Part 1, The Motherboard.
First things first, check all your components work with each other, you could even go as far as installing an OS.

Using some of the 3mm styrene, I used some of the original internals to make a mounting board for the motherboard. 

This section fits into the front of the case, and sits into a seating at the back of the case, it the rests into some of the internal metal frame at the bottom.

It took a few attempts, I had to keep slotting it in, then cutting a section down a little until it fit snugly.

Next I positioned my Mini ITX Motherboard, I left room at the top to allow me to plug in the port extenders that will allow us to use the external holes of the case later on.

A sheet of metal underneath the motherboard will allow us to earth the computer properly. Mark the holes of the motherboard and fit some motherboard mounting bolts. I actually used some screw fittings off some old serial and VGA ports, which are essentially the same thing.
