I can make the computer any size. I'll probably go with a mini ITX config for now. As long as I can tie in the radio, BT, GPS, Ignition, doors, and windows that will suffice. I think I have located all of the pieces I need, it's just the actual dash that's giving me the fits now.
I need to redirect the vents for a few reasons... One is obviously the default WJ location would put the vents right behind the monitor (not good especially in winter). Second is that the heat coming through the vents can cause a computer to overheat (if I install it in the dash as opposed to a remote location). Additionally, I am not confident that I can fabricate a different mounting method without swapping the dash out (aside from a mounted monitor which isn't what I am going for). I really need double din space.
Also, I just like the look of the WK dash better than the WJ's
