Is this USED gaming desktop a good deal?

[cdunwody]

I'm in the market for a new gaming desktop. I was going to build a new i7 system for around 1200-1400, but I stumbled across what seems to be an amazing deal. The following computer is being listed for $1100, so I am probably going to offer $1000 for it. According to the seller he purchased the system from Digital Storm just under a year ago. This seems like an amazing deal. How can I make sure there is nothing wrong with the desktop before I purchase it?

Make him sign a 30 day money back guarantee?
$1000???? No, no, no. You offer 700 and then deal from there.
It's a used system, I don't care what, why, or when, it is WORTH about half of what it cost new.(in parts, not what he paid for it. What HE paid for it is completely irrelevant, you don't care what he paid for it. If he starts down that line, just ask disinterested.)

Make sure its running when you get there. Ask to see some benchmarks so you can make sure its running like it should. A game or two with fraps and perhaps SuperPi should be fine. Once he is done doing that, shut it down and look at the parts. Is it really a Corsair PSU? Intel SSD? Two 2GB GTS285s? If ANYTHING seems out of place, back out.
