I had so much fun building my first PC. It's a monster of a machine. Aesthetically, I'm not finished. The only thing that bugs me a tiny bit is that my GPU is voltage locked, but it really doesn't affect me since its run every game I've thrown at it perfectly on maxed out settings.
The Xigmatek Dark Knight II has to be one of the most underrated CPU coolers; I've never seen my temps go above 45F overclocked and under heavy loads.
GPU stays nice and cool as well, only hitting about 70F overclocked under heavy loads as well and walks all over Tomb Raider, Bioshock: Infinite, Battlefield 3, Crysis 2, and any other game I've tried.
I love everything about the z87-I Deluxe and was surprised there wasn't many reviews anywhere.
A-Data SSD boots this beast up in under 15 seconds from the moment I press the power button.
I have to shout out pcpartpicker, and /r/buildapc on reddit (I've already posted my build over there). I really couldn't have done it without you guys.
