I'm thinking of buying the Corsair Air 540 but a lot of the reviews complain about the lack of filters and, in particular the holes at the bottom of the case. While this case would be on the desk, I've pets and I've had problems with hair getting in cases without filters and those holes just scream.... problems. Obvious solution would be to find a magnetic filter on the underside of the case. Does anyone know where I might buy one and/or if Silverstone's 240mm filter would work. The other option is demciflex but with international shipping fees the filters cost almost as much as the case.... Ideas?
