The Fractal Design R3 XL is a huge case. It's an E-ATX case that will fit oversized motherboards, more HDDs than you can imagine and a huge cooler. If you've got the money to spare, it the R3 XL will give you a quiet, minimal case that will have enough room for almost anything you throw at it.
Alternatively, an Antec P280 is also in the similar size and price category. That's what I use.
