At which interval should I empty my computer of residue, dust, and other not desired objects?
it really depends on what parts you have, a case with nice dust filters wont get dust as fast as one without but i clean my computer about once a month. i probably should clean it more often, i plan to replace the case to one with dust filters on all the intakes soon.
When would the perfect interval for it, and how do I know if my case includes dust filters?
reviews are probably the best way to tell, you can buy dust filters for a case though and if you want clean it when you think its dusty enough
Okay, I will read about it.
