This has a nice visual guide that requires you to know how to buy a raspberry pi, how to plug in a raspberry p, how to plug in an sd card (twice), and how to navigate to a url.
What about upkeep? Sure, installing PopOS is pretty easy if you follow the tutorial, but what happens if you try to install Steam one day and it breaks your desktop environment? Or maybe your sd card accumulates too much writes and corrupts your OS, and you have to diagnose the root cause?
I think you're replying to the wrong comment. This was a comment about installing Home Assistant OS, which shouldn't ever be a base for running Steam!
