Alright the instruction manual for the harddrive I got (seagate 7200rpm 8mb 80gb) says that you have to use the seagate disc utility CD to boot the comp without out the hardrive then you just put the seagate disc utility cd into the cd rom drive and then turn off the comp.. and then install so the comp will boot up from the disc. So do I need to do this if I am building the comp from scratch? And if I do should I just instal the HD last? The problem with that though is the radeon 9800 pro wants me to connect to the Hard drives power connecter. So I need some advice... if I can't install the HD until I put the cd into the cdrom drive and then I have to sintall the HD how can I do this if the graphics card has to be plugged into the hard drives power connecter. I am in the middle of building so I would like an answer fast. Thanks
