That came out awesome! I would love to do that on mine and put the head unit where the ash tray is.. I don't know if I'd have the patience.. Good work.
The PC is in the trunk. This summer we're going to do up the truck with a fiberglassed box in the floor so for now the PC is just sitting back there in an Antec Minuet 2 case.
Armrest would work if your mobo was small enough. We used a MicroATX board which wouldn't have fit.
We don't have a head unit anywhere. The PC connects straight to the amps. We retained the steering wheel controls using an SWI-X which was already in the car from the previous stereo. It converts the button presses to IR. There are threads on the board about hooking the wheel controls to a computer through com ports, fyi.
Hmm I might try and mess around with angles sinec I have the dash off before I put it back on. That would be a lot easier than completely redoing the whole dash. Insetting it might have better results then I have on mine. Hmmm
