If neither an Atom 330 nor a cheap Athlon 64 do not offer sufficient performance, the new i3-530 and H55 chip-set may be a much faster alternative (with lower power consumption than the Athlon 64). This combination is more expensive (official CPU list price $113) but a CPU plus uATX mainboard should still be under $200 (e.g. the MSI H55M-E33, or if you want an ITX form factor mainboard, the Zotac H55-ITX). Idle power of a small system (incl. 2.5" disk) has been reported as low as 20W (primary power, efficient 120W power supply), with throughput near that of low end quad CPUs. Regards, STefan
