What I'd like to accomplish is to build (or buy a prebuild) a low-power system that I can keep my harddrives attached to and turn on when I need to access them, or when I leave for several days that won't suck too much power just idling. Right now I only have 2 2TB harddrives in my rig that are in raid1 to protect my stuff. I'd like to be able to transfer that raid (or rebuild if I need to) and connect it to my rig and be able to access info from the drives and when I'm out of town have the ability to stream music or movies from there without having to first download it.
I've been thinking of getting something like this for cheap because it also has such a low TDP (13W load for cpu):
plus I already have 2gb of laptop ram i could throw in there.
Is this is viable idea? I'd probably need to get a cheap sata expansion card since it only have 2 SATA connections and I'll need at least 3 (2 hdds + 1 primary drive)
I'm also not knowledgeable about server software but I've heard linux bases o/s make setting up a home server easy.
If it helps I can also get windows server 2008 R2 (or standard) for free through microsoft's dreamspark program.
