And the power consumption (in watts) would be what exactly, I don't remember where "superb" fits in the standard units, how many libraries of congress is that?

It's great to know it thrashes it's competition, but a real watt figure would be more useful.

Old PII tower, RAID/network cards as needed, a handful of HDDs and FreeNAS. Although a few pounds less to buy and more hours work to set up initially, being able to fix the damned thing when it breaks is worth (often literally) thousands.
