I think ExampleOne means well but plain vanilla SteamOS is not packaged for broad hardware support, easy installation or sustained desktop usage.
If you use the machine only or mostly for gaming, Bazzite should do it. It's a preconfigured SteamOS that installs anywhere except if you have an Nvidia GPU. You could also try ChimeraOS but I feel at the moment Bazzite is more polished. If you're stuck with Nvidia, waiting for PlaytronOS might be the only way forward.
If you also want to use it for desktop work and are a beginner on Linux, try any of the Ubuntus or Fedora, they're pretty much equally easy these days. On Ubuntu you'll have to contend with Snap packages for many basic components like web browsers, though, which are nasty, sad, stupid and evil (in some users' opinion) or the next messiah (in Canonical's opinion only). If that leaves a bad aftertaste for you, Fedora it is.
You'll find a lot of opinions in every direction so maybe head to gamingonlinux.com and join the forum, IRC channel or Discord.
