How do you keep dust out of your computer?

@MURD3RM0NK3Y yeah i do that to clean it. But how can i prevent dust?

@GuyWithOpinions I'll tell you in a month, I just ever-so-lightly used dusting spray on my keyboard and wiped it with a duster

1 day on, no dust, no ill effects on the keyboard

@RoxClymer the fans in my computer are gross. Feels like it collects a pile of dust every month

@GuyWithOpinions The thing is that you'll collect dust quickly if you live in a dusty or messy environment. You can't prevent dust from coming in, because you need ventilation.Everyone just clean them from time to time.
