Hi 'jhark515'
I am using the Corsair 'Obsidian' 650D as my computer case, and yes, it does have a front air filter (washable) for its 200mm intake fan.
I find it to be a great mid-tower case for my needs to include the 'hot-swap' capability (I use an HHD for my back-up).
My only complaints are that the front of the case does not have options for mounting other size intake fans (i.e. 140mm) and there are no dedicated SSD mounting areas (SSD's are mounted in the larger HHD trays).
