Also take pictures as you go on both dis-assemble and re-assemble. Also note which sata plug on the mobo the primary "C" hard drive is plugged into and make sure that it's in the same plug when re-assembling. Leave the rest of the hard drives if any unplugged till the system boots into W7. Take your time and have another system available to post an issue here if you have a problem and also have a digital camera so you can take close up pictures if needed. Have fun and everything will look and perform better in the new case. If you don't get the wiring perfect the first time that's ok as well as I guarantee you are going to get the upgrade bug and when it bites it bites deep ! lol
