I added a link to a PDF that goes over the mobo / cpu and internals minus the parts already mentioned. The case is made by MAPOWER. It is the 1Ghz variety with fan, but you have to strain to hear it.
Here are some quick stats:
Dimensions: 250 x 194 x 60 mm.
Weight: 4 lbs.
I/O connections: PS/2 mouse port, PS/2 keyboard port, VGA connector, 4 USB 2.0 ports, 2 Firewire ports, TV-Out/SPDIF, S-Video, Line Out, Line In, Mic In, RJ-45 port, COM port, and LPT Connector
Aluminum anodized housing allows for excellent heat dissipation and a sleek modern look
The system is small and as previously mentioned smaller = $
Hope it helps,
