Huh, I had just been trying to look into whether there existed a "mini PC but with a GPU in it that's at least as good as the ones in game consoles."

(Or, to put that another way: fundamentally, I want a game console — a piece of well-integrated consumer electronics that lives unobtrusively in my entertainment center, hooked up to my TV, requiring no maintenance, controlled entirely with a Bluetooth gamepad. But I want it to enable me to run both 1. current-gen games at at-least-equivalent fidelity to the console ports of those games; and also 2. "all the games a Windows PC can run." So, anything on Steam, yes; but also, all the weird little indie games on itch.io that never make it to Steam; and old DOS/Win31/Win95 games (either as polished ports from GOG, or through various forms of virtualization/emulation I'd set up myself); and even the little freeware games floating about on the "old internet", that someone made in Game Maker or RPG Maker 2000 or even as a standalone Flash projector executable, way back when.)

The closest thing I had found to that description so far, that even might work for the use-case, was the ROG NUC.

I wonder how this compares to that?

We have the ROG NUC and absolutely love it for our living room. Not playing any crazy AAA ultra graphics games, but it's been great.

If I had known this was finally releasing, I would have waited though.

probably exactly what you need! :)
