Utterly pointless building a PC into your car mate. Just another thing to make your car more nickable and why bother when you could just use a laptop?
Fair enough if your wife had kicked you out the house and you were living in your car.. or you were a business man that spent most of their life in their car.. apart from that it's pointless if you're in your car too busy driving!
It is still a cool project though to use to learn things.
Also, why would you want to game on a PC in a car?! it's physically impossible

Just build an xbox into the car. My mate has an old xbox crystal built into his which works well
