for my case i know for sure that i wanna get case fan filters so i dont get all that poopy dust in my case and i saw the aluminum case filter (at places like caseect, directron) anyone have them? im not sure if this would cut down too much on my airflow. I know they would if they were full of dust but i plan on cleaning them =). they seem like a good deal...keeping case dust down and also acting as a finger guard for intake fans. tell me waht ya think!
