You have a lot of cases here that are fundamentally different from one another.
I would most likely pick the P182, but that's just my personal preference. (I actually might not pick any of these due to size constraints at my place, but if I were working in an ideal situation I'd probably go with the P182.) I like the way it looks, it has good cooling capability and sound characteristics.
However, if you bought it you might end up hating it for being boring or whatever else. It's certainly a different style than the Nine Hundred or Tempest. The Cosmos has a different aesthetic than any of those.
You need to be more specific about what features you want in a case for this thread to be truly helpful to you.
