So I've run some cat5 down to the garage (uh..by drilling a hole in the floor of the bedroom. Don't tell wifey..s`not our house anyways. We rent. ha) and I stuck a hub down there with the intent to run a windows server for restarting my BBS (ooh yeah. Legend of the Red Dragon, baby). I'm also entertaining the idea of running some sort of Network Attached Storage software so I can have a rather big-arse hard drive(s) to store movies or other large files that I want easy access to but not necessarily taking up space on my desktop PC.
It appears as if I have a few options. FreeNAS and NASLite look good. But I'm looking for in the end, is the ability to open good `ole My Computer and see a network drive.. as seen below on my work lappy.

Am I on the right track with those NAS systems listed above or do any of your foo`s have other suggestions?
