I assembled this PC for myself. I play many games like Battlefield 4, CSGO, Skyrim, Rust, Dishonored, LoL, some Assassin's Creed, Far Cry 3 and other games. It works very well, it's fast and I can play all games on high-ultra settings, having above 60fps costantly. The CPU temperature in idle is not bad but I want to change the thermal paste with an MX-2 and I wanna add some fans because summer is coming and is so hot. Don't worry about the temperatures of the 960, I calculated when the fans were off. I bought the non-windowed version of the famous 300R because I made the tempered plexiglass window myself. I also added some sleeves and a RGB LED strip, connected to one molex of the psu, just for make some cool light. I had some problems in this build: the HDD is loud when is working, the PSU fan makes some noise and most important, I have graphic bugs in some games, and I see darker colors green and purple...but I'm glad of this build, guys if you have some comments or advices, please write here.
UPDATE - 25/06/15 Finally my new Corsair RM550 power supply arrived today. I've already mounted it, it's very very quiet and has good aesthetics, but I had some little problems with the cable management. I also changed the thermal paste with an Arctic MX-2; Idle temps aren't changed, but I get a few degrees less in gaming. Photos coming soon.
