[G-spec]

So what material would you guys recommend that I use to cover the side of my case...something that allows good airflow... I'm planning on taking off the whole left side cover because everything runs at least 15c's cooler since the computer is right next to my window. And that's on summer nights, winter nights I'm expecting it all to run even cooler. All that cool air coming in makes a huge difference... I still would like to put some filter type material to keep any particles out, has to be big enough to cover the whole left side of the case..

I wouldn't do this if the diff is a measly few Celsius, but upwards of 20celsius cooler is big
