Can this be done at home on the cheap? I'll build my own NAS setup if it's easy, etc. Looking at something I can tuck away seperate from the main PC just for peace of mind. I need about 1TB - 2TB would be better though. I know nothing about this other than looking at $700 systems on Newegg.com. Any links or sites where I can learn about this stuff or does anyone have experience with this? Thx!
