Absolutely no complaints. I had been looking for a desktop that would be better than my current laptop and got recommended this tower by a friend of mine, and we both figured that it would be a perfect upgrade for me. It's incredibly fast, very quiet, and runs all of my games with no struggle at all. The only thing to really feel concerned about is the cost and investing a good portion of money into it, and then wanting to make sure to take care of it well so it lasts as long as possible, but I'd say that it was definitely worth the purchase, and I'm very glad to finally have my hands on it.
The shipping was also pretty solid, it had pretty much arrived the day it said it would, and it was well boxed up. As it said, it came in excellent condition with extremely minimal scratches and markings, but I'd only notice them if I looked very closely at the tower.
Overall, I'm very happy with the purchase! Now I just have to make back all the money it took to buy it...
