I'm trying to find some sort of material that I can use to cover the open side of my case. Its main role is to prevent (or minimise the amount of) dust coming into the case, while not impeding the airflow too much.

Now I know that the default response in these kind of questions is often "Keep you case closed, always!!!", but I've done some pretty extensive testing, and the computer is definitely a lot cooler with the case off.

Testing with a number of graphically games, the case-off temperature in the GPU (R9 280) never breaks 67°C, and usually stays in the high 50s. Case on, however, the GPU is breaking 85°C doing the same tasks.

Any suggestions for a material are welcome.
