Had a movie stop playing the other week (I use my PC as a Jellyfin server and watch on a Nvidia Shield in another room). I thought something had crashed, but when I went upstairs to check, it had realised nobody was watching it and fucking rebooted.
you should probably use a different operating system if you use it as a server
It’s really not a good idea to have a home server you don’t update, assuming it’s accessible outside your network.
Windows updates suck, but they can be delayed to only take place every 6-8 weeks.
Living room PC is also used for playing VR games (since living room has the space required). Sadly Windows is the only option.
Pure curiosity, I don’t own VR gear, does the Linux steam version not have VR?
