I am looking for a small case (micro atx or mini itx if possible) with a good set of externally removable filters. It will be a slave computer, so not much running on it, but will be in the grooming room at a doggie daycare - so lots of dust, hair, and dander floating around. I can find plenty of big gaming cases with filters, but not many smaller ones. Does anybody know of a solution? Many thanks in advance.
