Well, I'm the stupid one here. My dad is actually very helpful and thought of a bunch of things that I never would have. That and he actually has some woodworking skills, unlike me. But originally, this was going to be a ghetto piece of flax.
Anyway, we've made some progress. First off, the control panel. There's a bit of a story here. First I built a nearly identical one out of 1/8" hardboard. This one is 1/4", thicker and more rigid, but I accidentally drilled four holes for the P2 small button cluster (start, select, pause, exit) instead of 2 (P1 gets all of them, P2 gets start/select). It turns out the 1/8" hardboard works fine anyway. So, actually using the PROTOTYPE, not the actual one, as little sense as that makes. This is the real one which won't be used (note P2 small button cluster). These buttons suck, by the way. Huge amount of resistance.
The cab so far, with control panel module held in place. My dad is pretty much responsible for building both, all I did was drive some screws in and drill a bunch of holes in the CP.
A diagram to help you get a better idea of how it goes together. The L-shaped pieces of wood will hold the motherboard tray, and the upper pieces hold a shelf that holds the monitor mount or something like that. To give you an idea of size, the cab is 18" wide, 22" tall, and 12" deep (bottom section). The CP is 24" wide, 4" tall, and 8" deep.
