Does anyone here have any experience of the Fit PC 2 ? They are getting almost reasonably priced now - CPC have the Linux one for £285 (plus VAT) which for a really tiny and low powered machine isn't at all bad.
Power consumption is 5 watts, it has 1Gb of memory and a 160Gb hard disk and Gigabit ethernet. It would thus seem to be quite a good basis for various Linux based "boxes on the network". It comes with Ubuntu 8.04 installed.
