Well...that nano-ITX looks to be the shipping version of the prototype board in the CES car computer I built and posted earlier in the thread. Glad it's come to market. It was easy to work with, and stays very cool.
- It runs off 12v directly, but for car use I'm pretty sure you should add a 12v power conditioner with auto ignition start/shutdown - mp3car has a bunch, haven't tried any myself.
- I used the on board VGA header, just needed to move some pins around in a Lilliput VGA header kit. HDMI would have been better, but the cabling didn't fit my build.
- For video playback, look for apps that use UVD acceleration and EVR rendering - WMP and WMC and Cyberlink are examples - this gives HD playback with low CPU utilization.
- I got the best Windows 7 visuals on the 800x480 7" Lilliput by setting windows to 1280x720 to get everything to fit on the screen, then setting the DPI in Windows to 125 or 150 to make the fonts bigger.
