Fry's got in a cool new barebones box in mid-December called the
SpaceShuttle. Here's a link to a nice review of it:

It's from a company Shuttle Technologies in Taiwan, and it uses a
motherboard available from from them called the FV24. The barebones box is
around $230 wholesale, and the motherboard is about $100.
I'm thinking ... you could slice the top half of the box off of the
enclosure and still have room for a 3.5" or notebook drive and a second NIC.
Imagine .... a 1GHz P-III, 1/2-GB RAM, 40GB HDD, 2 NICs, audio, video, 2
firewire & 4 USB ports, all in a box the size of a 2" thick book ... for
under $300... not bad for something like a "home server appliance", eh?
(The ones on the market today are 200MHz Z8 clones.)
