My home server (600MHz fanless Eden processor, 1Gb RAM, 320Gb HItachi IDE drive) draws only 24W - 32W. Even though the processor is a dog compared to the Atom, it's quite adequate for the usual file/print sharing, email, web proxy use. In other words, a small office could use it without losing patience.

I think we are suffering from Intel's usual blindness around the embedded/SFF business, as the 945G chipset is plainly unsuitable for SFF use.
