I've recently opened up my case, which I haven't done in a long long time, and I found quite abit of stuff in there. If it were just dust, I wouldn't have mind alot, but having said that, I might just say I found: 1xbeetle, 2xhousefly 1xmoth, all in the casing. Dead of course, but how did they get into my 24/7 running comp or into the room in the first place is a mystery. Not too many insects in Australia, especially with all that mesh at all windows and doors. Anyway, I was thinking, is there any way we can just reduce the amount of fust that goes into the computer? here's some suggestion (feel free to add your own): 1: Get a filter at each air intake. Works best when all other intakes are sealed. Scotch tape helps at those small holes near the base of the casing. Pros: no dust in computer, no insects neither. Cons: reduces air intake, may cause overheating. 2. Get an ionizer, and put it into the computer. How exactly this will work, I don't know, but hopefully it'll attract all dust on it, reducing the total number of items needed to be cleaned. pros: no dust in computer, doesn't affect airflow. cons: may cause damage to computer from static electricity, doesn't work with insects. 3. Vacuum seal the computer, and use watercooling. pros: keeps 100% dust and insects out, might even look cool. cons: expensive, makes accessing inside of computer hard, might cause other components to fry. 4. Live in a place thats less dusty. Places include: marshland, Greenland, both poles, and Atlantis. pros: No dust to worry about in the first place, doesn't require additional components. cons: Moving costs, new place may be less comfortable, may require the skill to breathe underwater, computer might not work underwater. Also doesn't solve problems with insects. Before attempting any of the above, please weight the pros and cons, as highlighted. I will also not be held responsible for any damage to your computer as a result of implementing any of the above. Batteries not included.
