Purchasing is an opt in too. I use both but paid for a Plex lifetime pass almost 10 years ago. It was easier to set up remote access. Setting up a server was new to me at the time so anything I could find that made it easier was worth it. I also bought an unRAID lifetime pass for the same reason (among other reasons).

I’m not sure. I’ve always wanted something like Plex but for games.

What about Sunshine and Moonlight? This is something I’ve been mildly interested in for a while but never took a deep dive.

Thinkcentre Tiny, Dell Optiplex Micro, or HP ProDesk Mini. Prices have gone up the last few months but they’re still a solid value. Most sellers ship pretty quick these days.
