This is really cool and basically a Mac-Mini clone, but it can take a Penium M and run Linux or Windows XP. It's the same size as the Mac which is awesome. The only downside would be the power supply since you can't easily integrate an automotive one I don't think. I usually don't like pre-built computers, but these tiny ones are cool and would save a lot of time from building one. Being a programmer and computer tech, I'll probably still build my own. If an automotive power supply/shutdown controller can be integrated easily, I may change my mind.

Aquired one of these a few weeks back, very good quality and very compact packageing.

That one is cool too. The only problem with it though is the length. Mine will be going in the upper cubby, so I'm still probably going to have to make a custom enclosure. What did that one run you if you don't mind me asking? And where did you put it?
