I'm highly debating going back to air (or a closed loop system) for the current build I've been planning. I've been trying to figure out what cases these days provide the best cooling, but a lot of reviews I've been looking at don't test thermal performance, and some that do only include a handful of cases so it's hard to get a good picture. I have a budget anywhere from $100 - $350, I definitely wouldn't mind keeping it under $200 but if I found something with great cooling, is nice to work with, and looks decent, I'd happily pay more. And I don't mind forking out to add/replace case fans. So far I've looked at everything from the Corsair 900D / 780T, Corsair Air 540, Enthoo Luxe, EVGA DG-87 (no optical drive bay would be a bit of a problem for me but it's tempting otherwise), Cooler Master MasterCase Pro 5, be Quiet! Dark Base Pro 900. Aesthetically I probably like the last three best, but I like all of them enough that that's not going to be a deciding factor. Any suggestions? I was intrigued by the Corsair Air 740 after reading the [H] review, actually, but again the lack of a drive bay would be frustrating (I could easily buy a cheap external DVD drive, but I'd still be giving up my Blu-ray burner). Also, noise isn't an absolutely huge concern for me, it can't sound like a tornado but I've had plenty of cases without acoustic dampening that were just fine. It'll be cooling a 6700K and GTX 1080 FTW. CPU temps are going to be more important for me because I don't really OC my GPUs anymore.
