good start, and It's great that it's a budget system.

Great link for the car/DC atx power supply, I love it.

You don't NEED winXP for your setup, something with less resource requirments will run just as good, and boot/shutdown faster.

When I do my system, I'm going to throw a bunch of memory at it, that way, windows won't be using swap so much, and reading/writing the HD, which is your enemy in a bumpy car.

If I could get it to load entirely into memory, and just load data from a CD, I'd be golden Cheap laptop might be ideal for that (if it has suitable video outputs, I want to control 3 LCDs, semi-independatnly)

Keep up the good work, I like seeing the car/case-modding world meet.
