Im looking for a little computer to fit in my glove box or even my trunk i need it to run HP tuners and maybe itunes or some other music program. I was wondering if it would be better to put my own one together or buy a pre built one from here http://store.mp3car.com/Car_Computer_Systems_s/25.htm Im going to run it to a 7inch screen in place of my cd player and before everyone says its not worth it id rather have this built into the car instead of using a laptop. I want this so i can constantly run my tuning software (HPTuners) to log and switch tunes when ever i fell like it.
