Soldato
Because i thought it only came with one for the bottom, although since the vents cover a larger portion of the side panel now maybe i could stick one of the filters beside the included one to cover more area.
Or does the filter cover the whole vented area?, probably will be fine with just the included one i think.
The filters cover the bottom of the case and the top half of side panel (where you attach a rad and fans), as that covers where air would be pulling in. The rest of the vents would usually be passive exhaust, hence no need for filters.
If you want to cover them up anyway at the cost of airflow you'll need to find something to adhesive them since aluminium isn't magnetic.
