A few years back now but I do remember a computer that was sold in PC World it was for Video work the front of the case had slots and you could put drives in a hot swap and just slide it in and out this allowed all you're current work to be saved on to a drive then this drive could be removed and put some where safe I my self had a computer that used a large enclose to keep my self up and running. Now days I use a mate to back up my system drive on to an USB drive it works for me.
