Best airflow case?

[Digital X]

After putting a 290 in my case, it's getting pretty toasty. I didn't plan outright of putting the card into my case when I had my 760 (but wanted to upgrade)

ATX, under £100 please and as many fan locations as possible. Will be looking at Noctuas's. MY GPU is 44 degrees idle, with CPU at 34. In the long run looking at the Z97 route, hence ATX.

Silverstone RV02-E is about as good as an air cooling case gets, but it's not that roomy inside despite it's large footprint.
