We finally finished our review of Shuttle's KPC K-4500, the Foresight Linux-based small form factor desktop that Shuttle announced a few weeks back. This review covers the lowest end complete system. Shuttle also offers a bare-bones K45 model (with no operating system) as well as a few others with higher-end hardware and Vista Basic.
As for this model, tread lightly if that $229 price tag makes you think it'll be good for the kids or the non-tech inclined. Not that the Foresight Linux operating system is hard to use, it just might require your help to maintain (try asking a 5-year-old to install a DVD codec, for example). But if you're looking for a cheap, complete Linux system, or you simply want a small PC to knock around on, the K-4500 offers some remarkable bang for your buck.
