Long post alert:
I don't like the exterior design of the NZXT case, but that's just a personal preference. The case I mentioned owning earlier, the HAF X looks great in my eyes, but other people think it's ugly. I happen to dislike the look of the NZXT cases in general, and tend not to go with their cases, so I have never owned or looked in depth at an NZXT case.
That said, I'm sure either case would do a fantastic job. Since the NZXT is a larger case than the Corsair, it has more 3.5 and 5.25 bays. If you have a lot of hard drives, that may be a part of your decision. I am partial to the Cooler Master cases, since all of my experiences with their cases have been good.
I recommended the HAF 932 and 922 earlier, and stand by those recommendations, but when choosing a case, a lot of it comes down to your personal tastes. Which of the cases in this thread would you rather look at on or under your desk?
Size is also a consideration. The NZXT and 932 are full tower cases, and are taller than either the Corsair or the 922. The only thing about the 932 is that it is significantly on sale right now, and the current price may not last too much longer.
Both of the cases in your latest post are good, highly reviewed cases. Any of the cases in this thread will get the job done. Now it's just personal taste.
