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.

Radiators? Nah, open loop. One end to the faucet, other end to the drain. If you’re on well water it goes right back down to where it came from.
