Those ITX boards actually can be ordered with DC power inputs (complete
with auto shut-off/ignition kill/etc). Just use a PCI tuner board in the
case. But even so, its still a PC and you're going to have trouble when
driving around because neither the case or hard drive or components
inside are built with auto-use in mind (i.e.
shock-proofing/vibration/airflow). ITX cases also can't hold up against
heat, and the PCI tuner card will cook the hard drive and CPU no matter
where you put it in a car.
