The Corsair Graphite 780T full-tower case is on the test bench at Overclockers Club today. For comparison purposes, you can see our evaluation here.
First up, having support for every aftermarket CPU cooler is a major advantage. When I say every single one, it's because nothing has topped 200mm yet and that would just be purely insane. I have time and time again given advice for purchasing a cooler, only to find out that a height limit is an issue. At 200mm and a good amount of surrounding space, there isn't much that will not fit.
