I know, but...i'm disabled with a farked back...so opening my case frequently to clean filters is not wise for me. :sad: Unfortunately, i'm better to do a thorough cleaning once or twice a year...get all the pain done and over in one cleaning. That's why it took me ~ 5 days to tear it down, clean...add some extra holes in the mobo tray, and rebuild. I can only do so much at once. :help:Dood you really need to invest in some filters. Will save you hours of labour. But it does look good now.
