My parents need a new rig, and so do I. My budget is somewhat tight, so what I will do is build mostly a new rig for myself, and give them my old one. (which is more than enough for what they use it for) My question is, can I take their old hd, and put it into my old computer, and then take my old hd, and put it into my new computer? They have Windows ME on their old hd.
