Ideas on this build

Solution
The rosewill quark is a fantastic PSU, and the S340 is one of the best mid tower cases on the market.
Bigger doesn't = better, and Corsair aren't necessarily the best in quality.
@envy14tpe, I selected different components and put in a 1080 instead.
Build looks good but I wouldn't get an enormous full tower. Only time I see is use is with multiple GPUs and tons of HDDs. For your build a mid tower is better suited. Also, i7 will help in BF1 and other games.

500GB of SSD space is overkill for a gaming rig, leave it for software and OS only, it doesn't improve game performance, only loading times.

Can u stop making two posts when it can be done in one? If you can do better then just show the post the first time.

Anyways, it looks like you chose the i7, H7, midtower, as I did. Good thinking.
