[SOLVED] First Build Idea

Solution
That looks good. I would probably look at a different case though. If you absolutely have to have a 5.25" drive then the Phanteks Enthoo Pro M or Corsair Obsidian 750D would be good ones. But if not then you're better off with something like an NZXT H500, Phanteks P400, or Fractal Design Meshify C.

The need for 5 1/4" bay does limit you a bit. If it's not a must, NZXT H500 case is $70 and it's a great design. It also doesn't need any additional fans based on Gamers Nexus testing. For power supply EVGA G3 can be had for $70-80, and is a fantastic unit. Finally, if you are looking at 144Hz gaming, I'd look for 1070 if you can find it cheap.
 
These are the changes id make to the system, to allocate funds to a high refresh rate 1080p gaming system:
