Go to www.antec.com and look at the Antec P180 Performance series case. It has 2 plastic snap in filters on the front of the case and all you have to do is run it under water and shake it out......bingo your back in business. Also it is whisper quite too
In 4 months I might have gotten a lil bit of dust in my box but only from opening up the side panel once in a while.
