hello, i recently replaced the fans in my cse to go along with a blue LED theme, replacing the weak multicolored fans that came with the case. i do have one multi left tho, its right across from the video card. i just bought a vantec spectrum cooler tho, so i think its now unnecesary. i would like to remove the fan, but what can i cover that hole with? i doubt that metal grill will be affective in keeping dust out without a fan being there. is there some sort of mesh/filter i can buy that screws into that sort of space? heres a pic, and the fan i will get rid of is squared in red
