Thanks everyone for the help! Im just looking for the easiest setup possible to have many external hard drives around the Mac Mini as a HTPC.
Im looking at Drobos too, but they have such bad reviews and they are very expensive. Thats why I thought maybe it would be better to just buy external hard drives and put them together around the Mini. It would be a LOT more cheap, but then it would be a mess of cables and stuff.
