Yesterday, newegg had this http://www.newegg.com/Product/Product.aspx?Item=N82E16817148041
low end power supply for $25 after rebate. Notice the 13 amp 12v rails versus the 650w rating. If you believe this, I've got some prime swamp land in florida I'll sell you. And this unit is better than some of the units that come with cases. The only cases that have halfway decent power supplies are made by antec. Most of the others are overated and could fail under load.
