I have a dvd rom, speakers, monitor, and software. My total if I go the cheapest way of all options on there is $719 so far. Am I missing anything? I mean I'm thinking extra fans, possibly a dvd rw, anything else I could need you could think of?

I don't know how far I would trust Rosewon't. I might skip the Audigy and get a MSI K8N-NEO Platinum. Good 7 channel sound, a ton of extras, and none of the non-adjustable memory complaints people are lodging against the Gigabyte economy boards. Logitec MX-510 for mouse or Intellimouse Explorer 2.0. Kingmax might be OK but make sure you can reach at least 230mhz with it as you are surely going to want to overclock that pig! JMHO
