Hi, i've been looking for info on making my own dust filter, lots of places suggest pantyhose and wrapping it around the fan and using an elastic band to secure it. The problem is half my side panel has holes so just filtering each fan won't make a difference. What would the easiest way to filter pretty much hal,f the side panel be,i was thinking of making a frame or sumthing and screwing it into the panel but then the fans would have to be screwed through the filter making it a mission to clean. Also tohught about magnetic strips but no idea where to get those. Any ideas?
