You cannot tell me that installing a dust filter for the main intake (the front optional 120mm fan) will add much to the manufacturing costs. I wouldn't even worry if it was a manually installed filter that you have to unscrew or pop of the front to access. Just a few little metal clips and 5 cents worth of plastic will ensure that the case doesn't become a dust vacuum. It my firm pre-req for all cases (even cheap ones). No intake filters, no purchase. < /rant>
