So I have ordered my parts to build my new rig. I am using the same psu (750 watt) with 8 pin connector and 24 pin hook up, same hard drives (raid config at 600 gb), and same sound card. I'm replacing the motherboard (with a z68), ram, video card, and putting in a core i5 2500k. My question is, will I be able to use my current hard drives to install windows 7 on? If so do I have to wipe the drives some how before installing the new mobo and attempting to install windows 7? The connectors look the same on the new mobo, as my hard drives are from around 2007 era. Any help would be apprieciated thanks.
