What are the rubber circles for on the back of my pc case? Should I just leave them like that if don't have a need for them? Or are they likely to let I'm dust into the motherboard?
Edit: thanks for all the replies, so just for water cooling I have no need for.
If i could show you the amount of awful 5 gallon bucket, recycled tygon and aquarium equipment "water cooling" loops i used to use for shit, you'd probably piss your pants laughing.
Found it.
Speaking off cooling and piss, I once saw a streamer experiment with cooling a pc with his piss. Well, I'm saying it was his piss. For ToS reasons, he made it clear he couldn't say it was his piss. It was ill-conceived and he couldn't get far enough to actually do a benchmark test.
Ah, it could be dubbed the Bear Grylls mod.
