Been reading slashdot?

It's a bit of a monster. The chipset still is the old stuff and draws heaps of power. But to be honest, in a car, low power is not exactly a priority IMO. A couple of amps (i.e. 20-30W) isn't much in the big scheme of things. It does mean bigger PSUs though.

Mini ITX is still way too big for a in dash machine. You need to be looking at nano-ITX or even pico-ITX.

I don't see that as a good fit at all. (my 2c)
