I love my R4!!! Its a very clean and quite case. There are lots of room inside, you can fit a slim 240 Rad up top and a slim 280 up front. My 7970 fits in the case easily even with the HD cage installed.
Fractal Design also has awesome CS. I tripped over my headphones and broke the front audio jacks. I called CS to buy a replacement and they shipped me a replacement free because it was a warranty repair, even though it was my fault.
