Need advice on new rig, must be UBER-SMALL!

I'm just about to move into a new apartment and I am thinking about setting up a new rig to use as a home server. It doesn't need to be anything big and fancy, I'll be using my laptop for most of my work. The new machine will more than likely sit beside my desk and be used as a file/web server, under network control. I was looking at the VIA mini-ITX (800Mhz) machines and thought that they might fit the bill pretty well espically considering that they are nice and small which is a BIG plus. Before I go jumping into a new system though I thought I'd ask you guys and see if you has any other suggestions for a VERY small machine. Retailor websites are also welcome. Thanks guys.

What's up cryo? Have you seen this article on Toms Hardware?

I believe that is what your looking for. I'd consider using it for building office machines for my boss but it is a bit expensive. Hope this helps.
