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.
Those look like optional expansion ports cut into the case that were filled with plugs because the configuration didn't need them. The shape I'd really odd though since the only thing that comes to mind is that they were intended for additional power cables - the shape is weird.
Edit: Downvotes for attempting to answer the question... awesome.
Downvotes for not getting it right, I presume.
Which makes me concerned that the "Hole for Pepnis" answer has so many upvotes.
Although it is a gasket for an optional expansion that wasn't included - it just appears I was wrong about the type of cable.
Being slightly wrong means more of an endorphin rush when people realize they can pounce on the flaw they've spotted, I guess.
Don't sweat downvotes, they're especially meaningless on the Fediverse. I happen to like a number of applications for AI technology and cryptocurrency, so I've certainly collected quite a few of those and I'm still doing okay. :)
I imagine downvoting incorrect answers being pretty useful in this type of community, it's nothing personal and as you said, it doesn't mean anything. Though just not upvoting would be sufficient.
Downvoting partially correct answers discourages participation and we're not reddit.
Only if you care about it. I can see why people do care, but there's really no need to, especially in this enviroment.
They are for watercooling, but you are right that people don't need them. OEMs just add some holes or a random reservoir mount and then bill a case as Watercooling Readyβ’οΈ, even if it has like, space for one 120x15mm rad, lol.
