Am I the only one who gets this I hoover regularly, keep my house fairly dust free (asthmatic), and have to clean my PC pretty much fortnightly. I wouldn't mind so much but I have to undo 4 thumbscrews on the back and 16 inside just to get at my filters I'm not the only one am I???
lol, no, we just like the dust no real way to get around the dust, but a good way to reduce it, is put the filter on the inside of the case so its Case>>Fan>>Filter>> and use HEPA filters. You might have to go get some small vacuum cleaner ones and hack them up a little but it would be worth it for you since your asthmatic.
Oooh that reminds me to clean out my dust filter. Mine's nice and easy to remove on my Lian-Li. I just have to pop-off the front of the case (no screws required) and then slide off the dust filter cover.
mine are all external, which makes for easy cleaning, not so nice to look at, but it tucked under my desk anyway so im not worried at all.
haha, I've got asthma and hayfever too. but only 3 thumbscrews allow me in to clean inside mine I've got no filters though, I have to use a small vacuum attachment which works well, just have to be careful eh but afterwards I start sneezing like hell. Just get a keyboard vacuum cleaner and use it carefully in the case. Just don't go too close to ramsinks on video cards
