Midsized case with filtration?

[Charlie98]

I love my HAF922 case... lots of room, lots of cooling; except for the amount of dust and dirt that's going into this thing. My house is fairly dusty (our windows suck) and I'm already seeing issues with dust buildup internally. I'm actually down to 2 fans... the bottom fan and the top exhaust fan, I have the others shut off trying to keep some of the crap out of this thing.

Who makes a decently workable case with filters? I've seen some of the Corsair cases have filter panels but their literature doesn't really emphasize their filtration value, and trying to wade through the manufacturer's websites finding information on this has been a little frustrating.

Does anyone know of or have experience with a good mid-sized mATX/ATX case with some decent filtration? Overall size doesn't matter (as long as it's no bigger than the HAF922!) but I don't need a $300 case, either.

Edit: I need 3 external 5.25", 3 internal 3.5" bays.

Wouldn't you be better off by purchasing or creating filters for your current case rather than looking to another case?

I've considered that, but the big 200mm fan up front isn't the easiest to access... I think I have to pull the whole front panel off to get in there.

Along those lines... are those little mesh screens they sell, do they work very well? My other thought would be access to the filter/screen once it's installed; I'll need access to it to clean them on a fairly regular basis.

Antec P280. Size is approaching that of a full tower, but it has excellent filtration.

The R3 has tons of dust filters. Two on the front for the intake fans, one at the bottom for the optional 140mm, and one for the psu.
