Eurorack cover?

Hey guys! Just got my first module today. The case I use is Cheeks of Power by Synthrotek, it was pretty cheap. It works but I'm worried about it's power supply and my module getting dusty. Idk if it could get messed up that way, anyone have any ideas of what I could cover it with? Besides a shirt?

Use blank panels to cover those empty spaces on your case, you don't want to stick your hands in it by accident and get shocked... For the dust, just use any cloth(cotton prefered, no static build up).
