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.

It's for safety, to protect any unexpected insertions, you first want to wrap parts in rubber. Otherwise you get a virus.
