I'm buying a gaming PC on Craigslist, help?

I don't think this build is that good... For one, the PSU brand I've never heard of, and the case isn't a good brand. But yes, the interiors are gold.

Thermaltake Toughpower at that power rating is a good PSU listed as a tier 2A herein:

Tier two class A - Excellent quality units, if not, as good as the Tier one class of units. For people who have a limited budget, but still want a reliable unit for the price

The Chaser A71 is one of the top-of-the-line Full Tower cases from Thermaltake.

Again, if the seller is being honest - and that is really the important pointhere - it won't be a bad deal. If you get concerned about the PSU you can replace it down the road a few months. JohnnyGuru (http://www.jonnyguru.com/modules.php?name=Search) has some reviews of the Thermaltake 750s and they don't get bad ratings.

Hm........... I don't know, actually. LinusTechTips made an ad about this but who says ads don't have lies? I guess if he wants, he could, but...

I would definitely pass. I don't like used builds...and it does not look like you will be able to properly check all the components are working before purchase since the hard drive is missing.
