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?

Besides the water cooling that’s already mentioned, those could be used for example for routing an internal device out and into the I/O of the motherboard. An example would be some fan/RGB controllers that are meant to be somewhere inside the case, but are terminated with a standard USB A plug (and very few motherboards have that as an internal connector). Another example is a mini display that you could put inside the case that would need to interface with the GPU (so you’d need to route a DP or HDMI cable out of the case and into the back of the GPU).
