[Beginner PC gaming questions.]

i generally tend to overthink matters every now and then so i need to ask about these items to get a better expertise and notice if i am right here.

how much should i worry approximately dust/hair etc. around my computer? i've my computer at the ground beside my desk, the ground is usually kept smooth being swept approximately every fortnight. 192.168.0.1

i plan to dirt out my computer each 6 months with compressed air. is this a very good concept?routerlogin

additionally, is it safe to do away with the usb connecting my controller and the jack for my earphones/headphones by using just really plugging them out? i recognize that with usb's you normally press do away with hardware correctly or some thing comparable earlier than plugging it out.
