There are a number of network-attached storage devices available (hint: seach on NAS). They generally work well, but are very expensive. As in: you could probably buy a cheap PC for much less.
So, that's what my recommendation would be: Buy a WalMart-grade PC, and put a big hard drive & DVD burner (for backups) in it, load FreeBSD with Samba on it, stick it in a closet and reboot it about once a quarter.
