Yup, that thing is way too big and expensive for what it is. I get the same functionality (NAS, media server, torrent machine, small DB server, small web server, FTP, git, SSH, remote desktop, caching proxy, print server, UPS monitor) from an $100 Atom mITX system with 2GB RAM that draws 50 Watts. I get 5TB of storage, available at 85-90MB/s through Gigabit. Why would I need more?

Also a benefit of the low power draw, a 700VA UPS can keep that thing running for about two hours.
