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.

    I used them on my old Build! Pretty neat if it got some light up the back, but I went back to air cooling, so I’ve got then holes of glory again.
