doubletoast for an update, bought everything on Friday (got the Rosewill PSU instead of the CoolerMaster), had it arrive on Tuesday to find out my hard drive is an ancient Ultra-ATA connecting pile of junk that belongs in a museum. Lucked out with a 1tb for $50 (ShellShocker from Newegg) and a $20 disk drive.
I think I've put everything together correctly without screwing up. All I have to do is install the OS and hope it works.
Now my main problem is getting everything off the old hard drive, which I neglected to back up.
EDIT: well this sucks, my old graphics card is in the PCI slot and the fan spins, but it's not being detected.
EDITII: Yeah I probably need a new card. Gonna use a 9500GT for the time being, but does anyone have suggestions?
