PC Master Race

One thing to note though is that SteamOS is immutable, i.e. / is blocked for writes by default, you can only write to /home, so you need to install things via flatpaks not via package manager. So not ideal for a power user, but should be enough for most people.

I disagree that Arch guys are the guy who tunes up everything, I think that would be Gentoo. I think Arch guys are the equivalent of the guy that built his own PC, it's not an impressive feat (even though some act as if they were superiors for doing it) and probably lots of the people who buy prebuilts can do it, they chose not to bother assembling things if they can get someone to do it for them. The reason I think this is because I use Arch for the same reason I built my PC, i.e. I'm lazy and want something that might be a slight hoccup to setup but will be a breeze to maintain, it might be a Frankenstein, but it's the Frankenstein I built and know.
