I’m not a computer expert or planning to be. I’m just a computer user, a coder, a gamer, and I think I will get the opportunity to afford cheaper PCs if I use the Arch distro from Linux which is very lightweight and fast. I’ve heard Microsoft forces you to bloat your PC with win11.
Arch isn’t exactly intended for beginners, and the “windows is more bloated than Linux” thing applies for pretty much every Linux distro.
If you’re willing to spend a significant amount of time learning and tinkering, a distro like Arch could provide what you need. However, if you’re just starting out, you might want to start with something easier. Distros like Linux Mint or Fedora are plenty lightweight compared to Windows, and they require much less learning to get started actually using your computer.
As for “which distro allows you to use the cheapest PC”, this mainly comes down to how much effort you’re willing to put in, not necessarily the distro you use. At a certain point, a desktop computer will “just work” for basic desktop tasks, the distro doesn’t change much there.
