Planning a NAS build as I need more space for my photos and media. The gist of it is a case with an ivy bridge pentium, a ssd as boot drive with 3 or 4 3TB green/red drives. Just looking for ideas on parts and software to run it. Planning it to be mini itx to save space, with upnp to stream to my htpc. don't currently have any redundancy solutions so any advice on that is appreciated.
