I am looking to outfit hair salons with new PCs and am looking for a smaller case with great dust filters and positive are pressure. i know thats asking a lot but its hard to keep these things from gumming up with dust every couple months.
Fair enough, basically I'd just look for any 'closed' style case with as little mesh/venting as possible and 2+ filtered fans included. Then change them both to intake and you should be good. They were just the only cases I could think of.
