Not sure where to post this but I made myself a fake Steam Machine from my Minisforum UM680. By which I mean, I installed SteamOS on it. I've wanted a console style TV based PC for a while and using Windows with a keyboard on my lap has always been cumbersome.
I've had this little PC for 3 years now (with Windows 10) and it has the AMD 6800U is a Zen3+ chip with a 680M GPU. It has 16GB of RAM (LPDDR5-6400) and 512GB of storage but I added a 256GB MicroSD card. It launched for $400 lol. I bought it for £329. It is the the size of two leather wallets stacked on top of each other:
Steam OS is a bit weird that it will first boot off a USB stick but go into a desktop like GUI environment. I guess running an OS from a USB stick is a linux-y thing. You then have to click on the install to install it onto the SSD. It's quite happy using an Xbox One controller.
It's performance is similar to the Steam Deck but at 1080p. I have a Steam Deck so I am familar with the interface and it is identical (as far as I can tell).
