It's interesting that you mention the 600T. I was almost set to order that case yesterday but I stopped because of users reporting that the front and top fans don't even intake/exhaust as much air as a 120mm fan, and that it is very difficult to find replacement fans for them since corsair uses low profile 200mm fans. That and the fact that a lot of people told me that it is overpriced, and that there are many better options under $120.
Right now I am having a hard time deciding between the 500R and the Phantom 410. Both are extremely sexually attractive but they each have something that I wish was in the other.
Empty space. Lucky you.
The 600t is the case that I had experience with, and it came with both a windows and a mesh side panel with mounts for fans. No having to decide between cases with either one or the other. I guess the case is a bit overpriced if the price is greater than ~ $150 and the exterior is largely plastic. The fan on top isn't hard to replace if you don't mind putting 2 120s in the top section. 600t cooling is another thread, especially if it's not something in your price range.
Which 6970s are you using and how much are you OC'ing them?
OR, you can get the 500r, and if you ever want a window just find/build one for it.
