Don't Increase My Cleaning Burden Please

Build a home system room at home is not easy. I found it quite messy also. I think hubby is not good interior designs. He knows how to set up the home theater but do not know how to use cable ties, clips, standoff and HDMI wall plate to make his home theater room in better arrangement. I am not really care about what he does to the room actually, just he has to make sure he does not increase my burden to do the cleaning work.
