It may be a little more expensive but it will be an absolute beast. You are looking at 5 years of high end performance. Or more, considering you can upgrade every component.
Only things I would change
The H60 is not enough cooling for that overclock. You need H80 or better, I'd personally go with the H100. Otherwise you will shorten your CPU life
I'd suggest a 1000W PSU so you don't have to upgrade in the future. Then you can add more drives and GPU power without worrying about it. It may feel pricey, but it is cheaper than trying to upgrade to a new one down the road.
What graphics card are you using? I'd highly suggest finding a used GTX 580. They are awesome for CUDA and a great price. very competitive with a GTX 690 in pure compute performance. And you can add another to upgrade later on
