Building your own PC with SteamOS is Missing one very important part for Home Media: propper CEC Support. This is something no DIY GPU or Motherboard has included Out of the Box. But it is very important for a good console like experience.

This is because of proprietary HDMI drivers

Accurate, but there are still a ton of mini PCs with CEC support. I have a GMKTEC K12 with 32gb ram running Bazzite. I'll probably slap Steam OS on it just to try that out and report back.

Did you try this out? I couldn't find any reliable information to confirm the K12 Supports CEC.

This would be a huge thing.

Not yet. But the K12 supports it. I set it up in the bios already, it's just that Bazzite AFAIK didn't get the kernel patch for it to work, at least on Bazzite 43. I haven't found the time to check if it's already in 44 or in the latest Steam OS version.

But yes, the K12 supports CEC.

You got any documentation from the manufacturer or BIOS Screenshots? I am very interested in that.

I'm away from home right now but this is what inspired me to try it:

Thanks for the information! Please post here when you tried it out and its working!

I would definetely buy the same device to replace my HP Elitedesk 800 G4 Mini for LibreElec to get rid of my extra remote. Should definetely work also 4k UHD/HDR streams.

Different instances act differently. Not every deletion goes through, both ways. So often enough what's deleted there isn't deleted here and the reverse.
