A very nice build for gaming. If you want it a bit cheaper, you can switch out the Cooler for a hyper 212 evo, change the case to Fractal R4, and/or get a bit cheaper motherboard.
Phantom cases are indeed cool but some of them are on the lower end of high-quality cases for materials. Like 410 phantom looks pretty cool but for me it had some metal bending at places and rubber grommets were a bit flimsy and that the case was bigger than i thought.
