I know this isn't the most glamorous topic but in my room it is a problem. We had a new house built and I have converted a bedroom into a dedicated theater room. I have covered the window and have my tv in front of the window with my reciever etc underneath in a stand. I put in 2 heavy duty fans to run to cool down anything in the stand. I do have a vent close to the system about 3 feet away. My problem is that the dust is unreal! I constantly clean all electronics with "canned air" and vaccum like crazy but the stuff multiplies like jackrabbits. I assumed that since the house was new that I wouldn't have this problem at least this soon. We did some drywalling in the basement a few months back and that might have kicked up some dust into the vents but that was some time ago. Any suggestions?
