630w Antec power supply. Not sure of the exact model number.

Will also come with a 1.5 month old HP w2338h 23" widescreen 1080P monitor. http://www.shopping.hp.com/product/display/display//3/storefronts/FN747AA%2523ABA

or

an Acer AL1916w 19" widescreen LCD monitor. http://www.newegg.com/product/product.aspx?Item=N82E16824009073

This thing is REALLY quick and runs damn near anything ridiculously well. It doesn't come with an optical drive, but a SATA DVD-RW drive costs like 25 bucks. It'll come with a fresh install of a registered copy of Windows XP Pro, Ubuntu, or Windows 7. Buyer's choice.

I'd like to get $750 for the computer, $825 with the 19" monitor, $900 with the 23" monitor. Pretty firm.
