I came across a bunch of those recently, which is how I came up with the idea for this, as a parody :)
Internet horror is disappointingly un-creative. I have no idea why the weakest works (sonic.exe, anti-piracy, kill screens) always end up becoming huge trends, or why so few people try to put a significant twist on said trends.
Tons of companies are shipping Linux without giving users access to the source code, it's just that only one has the term "Tivoization" named after it.
I'll probably use Codeberg or another Forgejo server for my next programming project, if/when I have one that is far enough along to publish (motivating myself to get that far is a tall task). Until then, everything I'd consider contributing to is either on GitHub, or is self-hosting some other software, so I don't have a reason to create an account yet.
Saru and Kelvin Spock would probably get along really well. Everyone else would be having heated arguments that I think would be amazing to witness, if not take part in.
I think I'd most like to sit between Mariner and Pike, though.
If you haven't set up this laptop yet, then I'd suggest installing a server-oriented distro like Debian, AlmaLinux, or Ubuntu Server. Those have minimal install options that come without a desktop environment installed, as most servers do not need one. If you'd like to make the install harder for yourself, this might be a good excuse to give Arch Linux or Gentoo a try, as those have the option of a fully manual install. If you'd like, you can install a desktop environment afterwards using the package manager.
If you already have a Linux with a graphical desktop installed, you can configure the system not to automatically start it with sudo systemctl set-default multi-user.target. (Do not do this on your main device!) You can re-enable it with sudo systemctl set-default graphical.target.
Regardless, you can then start a graphical session using startx, or whatever command is more appropriate for your desktop environment (gnome-session to start GNOME on Wayland, startplasma-wayland to start KDE Plasma), or by sudo systemctl starting your login screen manager (sddm, gdm, lightdm, etc).
I'm currently on the RHCSA path myself, and I can tell you that the courses are not worth the thousands that Red Hat charges. There are plenty of unofficial video courses on YouTube and Udemy and study guides and practice tests on GitHub that are free or cheap, and other resources for every individual study topic, which will be good enough.
However, though I can't speak from experience, it seems like the cert itself will look good enough on a resume to justify the investment of $500 and a month of studying.
Assuming you mean the Beelink S12 (which is the first thing that comes up in a search for "n100 mini pc"), that's quite similar to my own computer specs, which can run just about any distro, with enough resources to spare for a VM or two. I don't think it's necessary to go really lightweight or pick something special. If there's a distro you're already familiar with and know you can do all of those things on, install that.
If you like Garuda, you could always try a different Arch spin which is lighter out of the box, like CachyOS or EndeavourOS.
I've switched to FreeTube for now, it still works using the Invidious API. This is happening because YouTube is testing forced login to watch videos or use the API. There is a workaround it seems, but we'll have to wait for all the major clients to roll it out.
Windows 8.1 was my last version before I made the switch. Windows 8 was horrible. The Metro UI broke all my habits from Windows XP from 7 while also making it harder to tweak my system. By the time 8.1 came out, I'd found enough ways around the main annoyances that its improvements were moot, but many issues remained, such as the bloatware bundled with my PC, and frequent slowness and instability.
As for why I switched, I was attracted by the free software ideal, and trying to get away from Windows, and I had watched and read several things that further convinced me it was superior, but I think the ultimate reason was that I had become hyperfixated on Linux. Thankfully, in this case, autism did not steer me wrong. My level of obsession with Linux has declined, but I still enjoy using my computer much more than I ever did or would on Windows.
I have the same problem at my school, but thankfully, the school library has laptops I can borrow with the lockdown browser installed. It isn't ideal, but is there a similar arrangement you could make?
I've never used these, but I've come across them while scrolling through F-Droid and they seem to fit this use case:
