I've gotten 2 computers from Cyberpower. One was used bought on another website, and the other was just bought brand spankin' new from their website. It's very easy to configure your custom PC to how you want it, and if you configure the right model, it can be cheaper than building it yourself! The build quality is excellent, too. The components are very visible and nothing is obstructed, allowing for easy upgrading. I highly recommend going with this company for ANY new computer, not just gaming computers, as the great quality of Cyberpower vs. Dell or HP or Gateway is very noticeable.
update: Just got the new computer, and it arrived a day early!
