An update: I'm short on cash, but I was able to scrape together enough money to buy everything but the new processor and the video card. I also ended up getting a USB 2.0 card because the installed card is only 1.1. I expect to have the stuff on Wednesday. Also, I pulled off all the keys from the keyboard and cleaned them all individually with rubbing alcohol. The keyboard now looks brand new.
