One of the early things most people nnoticed around home server is it actually did not require much processing power to run it, the manufacturers have now taken notice and we are seeing a few home servers built off of Atom processors (usually reserved for netbooks or other mobile devices), the result? Home servers ranging from $299 - $599 in some cases including terabytes of storage.
