Got an ad for this today in my email. I know there are people frequently looking for hardware here I thought it would make a quite nice gaming box with a good video card:

Quite a lot of box actually for $700 IMO.
I've got a few System Max PC's in the past and if you're somewhat handy with hardware, they are a good bang for the buck. Always had good luck with these folks (same folks as TigerDirect and same SystemMax computers.)
