The only problem during construction was removing the stock 120mm fan at the back of the case to fit my Zalman radiator. The screw would not come out and thus got stripped.
This build isn't exactly new, just upgraded. I got fed up with my $50 Antec 100 windowed case, and my old GTX 660 Ti wasn't cutting it anymore. It didn't handle Battlefront 4 very well. I did not want to order a case online so I went to the local computer store and they had the Cooler Master Enforcer in stalk. and a demo computer with that case on display. I loved it. Well worth the $100 I spent on it.
I opted to go with the GTX 780 instead of the GTX 780 Ti, mainly because I didn't want to shell out $200 dollars more. Even though I could. I gotta say I am Impressed with NVIDIA's design for their cooler on the GTX 780. It destroys any stock cooling solution that AMD has on any of their cards. and it looks amazing to boot. That green LED logo on the side really makes it look nice. I also saw that the GTX 780 beat out AMD's R9 290X by a small margin in Linus' GTX 780 Ti review on YouTube.

The rest of the parts I got from Fry's Electronics in San Diego so far, being a year old now, they all preformed superbly. Learned a lot about computer building from it, and had a lot of fun doing it.
I use this computer primarily for gaming and graphic rendering as well as webpage design and photoshop
