Anybody have any project ideas involving mini-itx boards?(for anyone that doesn't know, a mini-itx board is a motherboard that's about 17x17cm). This one has a 733mhz VIA cpu and 512mb of ram...not a whole lot of power.

I was thinking of building a mini tabletop arcade cabinet, but if anybody has any other ideas I'm open for suggestions

(I already have a file/web server, and a media center)
