Make your own Intel Atom-based computer

Tranquil PC's D945GCLF Mini-ITX motherboard comes with a baked-in 1.6GHz Intel Atom 230 CPU, a GMA 950 video chip and a single DDR2 RAM slot; on the downside is the lack of HDMI, PCI express and gigabit ethernet. At $103, however, it's going to be stiff competition for the VIA-based Mini-ITX boards that are the mainstay of ultrasmall form-factor case modding loonies.
