I was so apprehensive about this purchase because the reviews are so hit or miss, but there was a crazy discount on it that made it under $700 and my son wanted a gaming PC for Christmas. I figured I wasn't out nearly as much as if I went another route so decided to try it and fingers crossed it worked on Christmas day. It has totally surpassed all of our expectations. I've never had to contact customer service so I have no opinion there, but as far as the PC itself goes, we have been more than happy with it. No issues AT ALL running any games and he's a teenager so he plays all the newest stuff. It's quiet, runs great, no issues at all. No clue how this thing is priced so low. Now I'm waiting for the price drop again so I can get one.
