I have a Dell Precision 690 System (Case, Motherboard, dual 5130 cpu's, 750w ps and 16gb ram) for sale. You will need two heat sinks for both cpu's. All you have to do is add HD's, CD/DVD and video card. Looking for $450 plus shipping. This is a big system and shipping will be around $50 or you can pick it up. Only selling because I will be upgrading.
