That guy is smart enough to mod XBOXes but dumb enough to hold onto and store 1,500 HDs?? Geez.... in the begining you could get some decent cash for them on Ebay, even a few years ago you could get $5 a HD. He could have build and sold some mini RAIDS for Pete's sake!!!
Even now, you'd think you could work some sort of bulk deal and get something for all those drives.
