So i would like to build a network attached storage "box". My question would be, is this possible. I really don't want to spend 400 bucks on a drobo, so i was interested in if i could get a network interface card, some how hook it up to 4 or so hard drives, attach a power supply, and then put it in a case. What i'm looking for are people who know where i can get these parts, and if it has been done before. I want to get NAS storage, but don't want to buy external hard drives for i have tons of drives anyways. Any input would be nice.
