They are all great cases - it just boils down to personal preference. Personally, I like Corsair, but that's just me.
As an aside, you might want to rethink your psu. Although the raidmax you list is passable from a performance standpoint, it is just a so-so unit. Also, 1000w is way overkill for what you are building, even if you go sli. My suggestion would be to look into an XFX pro, Corsair HX or Seasonic. Any of these in the 650w area would be just fine for your current rig and if you have visions of going sli down the road, move up to 850w.
Also, if you are planning to o/c, make sure you get low profile ram (no tall spreaders) as you will need an aftermarket cpu cooler and the tall ram will interfere with most air coolers.
