Nix is a big rabbit hole. You can use it as a normal package manager, but there’s a lot more.
You can also use nix-shell to temporarily install packages, it drops you into a shell with your package and that package is gone when you exit the shell. You can also declare a shell using a shell.nix file with environment variables and packages you want (including specific versions) and enter that shell by running nix-shell.
You can also declare your full user environment using nix home manager. Using a home.nix file you can list packages you need and configure everything. That also makes it easy to backup your user environment by just copying the home.nix file.
The GT 730 is a very low power GPU, it is even slower than many newer integrated graphics. I’m assuming you mean you have an i5 12400 CPU since you also have DDR5 RAM, which is a good CPU on a modern platform. You should really upgrade you GPU and maybe also upgrade to 16GB RAM as many games require 16GB and having 2 sticks of memory also improves performance by running in dual channel.
Not really a recommendation, but there are some professional displays for the commercial market that can have removable modules for its content. They are more expensive though and they’re more focused at being run 24/7 than looking slim.
Here’s a great video on one that uses a raspberry pi compute module: video
Other people have already said this in other comments on other posts, but in short Manjaro breaks easier than Arch because it ships stable older packages, but combines it with unstable new packages. The AUR can easily break on Manjaro, and ironically the same is true in reverse. Manjaro has broken the AUR before and they’ve let the SSL certificates expire, multiple times. The devs even suggested users to change their system clock back as a temporary fix. You’d probably be better off learning Arch itself or use Endeavor OS, although I personally haven’t tried it.
A similar thing has happened here in the Netherlands. Algorithms have been used to detect fraud, but had a discriminatory bias and accused thousands of parents of child benefits fraud. Those parents came in huge financial problems as they had to back back the allowances, many even got their children taken away and to this day haven’t gotten them back.
The Third Rutte Cabinet did resign over this scandal, but many of those politicians came back at another position, including prime minister Rutte, because that’s somehow allowed.
