Mounting The Board

The mounted motherboard

It was time to add the mounting bolts for the motherboard to the NES case. I needed to find the correct sized bolts to fit the mounting holes of the motherboard and also to be just the right length. After trying a few bolts I had lying around the house I ended up using some 4" 6-32 bolts and nuts. The 4 inches of bolt meant I would have around a 1/4 inch sticking up out of the motherboard in which to put some nylon acorn nuts to tighten it down.

I put the motherboard in the case and dropped a bolt through each hole so that I could mark where to drill. Luckily, all four bolts ended up in places where there was still case (hadn't been cut out to make room for other things) and not where any of the NES case legs were. After marking the locations for the holes I drilled them out.

I threaded the bolts in through the bottom of the case and locked each one in place with a nut. I also placed a nut near the top of each bolt for the motherboard to sit on. Some careful vertical adjustment of each and the board was sitting flat as well as snug against the back of the case.
