Okay here's a first layout plan.
So let me explain a few things. First of all I'm probably going to refabricate this piece of the console, or get another one from a junkyard or something since I've already put a few holes in here. Now the screen 1 and 2. This may or may not work with the touchscreen but I figure I can have screen 2 upright and screen 1 upside down and using NVRotate with an nVidia card I can actually tell it that monitor 1 is upside down. I just don't know if/how that'd work with a touchscreen.
The power switch is because I'd like to have one up front and because I'll need to do something with that switch if I have the PC handle the defrost.
The DVD location is fairly self-explanatory. I probably have plenty of room for two drives there actually, just can't imagine what in the world I'd need both for. If I do the Audigy with the frontside controls, I could put that there too. End up modding that tray to hold them.
