Here's my list of parts, all from the Egg (I'm loyal to em, built my entire first build from them a few years ago). I just bought 120 gig HD, WD at BB, $80 after MIR.

Will be scavenging DVD/CD ROM/Keyboard/Speakers/Mouse/Floppy from current machine.

Is this all I need, top to bottom, or am I forgetting something? (Do I need some kind of connector for the fan?)

I need the Win OS, mine isn't legit and I don't like that.
