You can buy filters seperately for about a buck per 120mm fan on newegg, don't limit your case selection based on that, you'll end up with a less-than-perfect case. Do that and buy an Antec, sorry to break it to you but FuLLBLeeD is 100% correct here. I have friends who own them too, and i wish i had gotten one.
Also, our definition of good is the same, we're definitely on the same page here. When I say "simple" I mean no stupid shit like fully transparent case with LED's embedded in the corners and shit like that...
My friend with an Antec has 11, yes eleven, 120mm fans in his case. It makes a deep deep whooshing sound, and cools the half of the room it's rear faces... There is a noticeable wind flow from it. It's wicked funny.
