The new steamos release for x86 is a nice start though. I was trying to run stock KDE before and and nothing worked with HDR and I couldn’t get any sound out of my TV’s TOSLINK output. Being able to run steamOS is probably a big improvement for out-of-the-box setups.
Could always just buy a NUC?
They don’t have HDMI CEC
