What CPU are you planning to use? Are you overclocking? For example, it’s a non-oc’d ryzen 5 there’s no point in getting slightly better VRMs but less features

G4560 is a better CPU and has better other components.

RGB always on can be normal, the fans are weird... Anyhow, you could try checking in BIOS how the motherboard handles the rgb when the PC shutdowns. Usually there is an option to keep it on or turn it off with the PC. It might affect the fans too in your case, but I’m not sure since they usually turn off.

The temperatures are fine, but I would consider putting the more power hungry card in the bottom slot for the extra air.

No, not really. Both could also support 144Hz, but depends on the implementation and if the monitor is 144Hz capable.

Learn the basics and then practice by working on your own projects, try to find something you wish it would be automated and create a program for it. You will start facing challenges on how to do x which is part of achieving y, find resources and eventually you will take in more and more knowledge. There is no beginner to master guide for anything. Being a master means having implicit/tacit knowledge. Guides offer you explicit knowledge, which only helps to a certain extent.

Have you tried downloading an update version of the bios and flashing it? Or doing a CMOS reset?

What did stress testing the RAM involve? Did you make a bootable Memtest USB and let it run overnight?

What’s inside? From the pic I can see a CPU cooler and no GPU. I would never buy a pc without knowing its parts.

You should only be concerned about temps and performance, not usage.

Can't you just put both routers in access point mode? (without chaining them, connect both to the modem directly)

If you have to find excuses you probably shouldn’t buy it. Just wait until the 3060 releases.

After so many results I would consider backing up your important files and reinstalling Windows altogether.

I would honestly go for an ever reliable ThinkPad.

Because you are absorbing the vibration with your hands.
