What are these, and why are they important?

I was tinkering with my PC and took these out, and I am wondering what these are, and why they are in there, it was a prebuilt so I had no idea what these are

Came home to this in the middle of my screen. Nobody else uses my pc. What should I do?

4 tb run out fast

Did I mess up my friends fan and radiator placement?

For context this was last year. I was building my friend's first PC. This was also my first time as well. I had knowledge but no practical work. They chose the PC case because they really liked it. If I recall correctly it was a NZXT 5 or something? From the looks of it, it didn't have much ventilation or air flow to its design. When I was working on their build, I was planning on putting the fans in front then the radiator on the back so that the fans pull in fresh air into the radiator but my friend wanted to "show off" their front PC case fans so I compromised and put on the radiator first and then added in the fans to suck the air from the radiator and exhaust into the PC. Since they've had it for a year, they haven't told me of any problems that occurred yet but I'm still concerned I made the wrong choice. Is this placement fine? How big of a difference would the temps be if I had originally gone with my original plan? Should I tell them and fix it up for them?

Back when I didnt know how computers worked

You think the NVIDIA Control Panel is bad just look at the NVIDIA X Server Settings

Caucasion women needed pls

I laughed at the absurdity, and then I cried at the certainty that there's an asshole somewhere who's already tried this. (with the correct comic this time!)
