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 is probably an old case design. In the early water cooling days, there would be separate watercooling units that sat outside the case. The grommets were so you could pass your tubing through.

    I wouldn't really worry about the dust tbh, you will wind up having to clean it regardless.
