This was a very fun experience to build. I'm pretty proud of it, and I'm also pretty sure I'll keep building my own computers from now on. This is in no way a perfect build and as such I'll cover the different things you could improve on it.
For those interested (I never know, someone might actually like this build :P) I would actually recommend you go with another design of the gtx 960 card because this one isn't the most effective at keeping the graphics card cool. Instead of the blower type, you could go for an open type with 2 fans and still keep the inside of the case cool.
Also, while I am very satisfied with the motherboard, the integrated "automatic" overclocking options are not the most reliable. Also, SLI is not supported, so if you want this option, the Asus Sabertooth H87 is another option.
