After my husband rebuilt my computer about four years ago I keep on complaining to him that it's a dinosaur. He says he doesn't want to waste of money on the one's that are out there when he can rebuild mine again with today's updated technology. I don't understand everything about the computer but I do know when he puts it together it runs super fast. One of the parts he says he's using is the crucial m500 120gb. This will give you the extra storage that I've been waiting for.
