I finally finished building my Small Form Factor PC and guess what? I installed Steam OS(Actually, the OS was originally for AMD Handheld devices since my CPU is an AMD as well as the APU which I heard is originally designed for AMD devices). Yes I downloaded the SteamOS and put it on my flash drive to install it on my MVME drive. I chose SteamOS because due to the console like environment plus it's stability with performance. It's not just a PC, it's more of like a console PC like hybrid in my opinion. Also you can navigate the menus using the Xbox controller with no problem since the operating system designed for the Steam Deck and other PC handheld devices. But that's not all
Supermodel runs very well on the Steam OS while using the AMD Radeon Vega graphics with the new 3D engine and surprisingly games like La machine guns which has heavy moments doing explosions runs at fluid 60 frames per second. I'm very pleased with the results and it's definitely a game-changer. Setting up the Arcade Emulators and getting them to work was a tedious process but, I'm glad so I can kick back and relax!
By the way I'm not running the Linux port of supermodel. I'm running the windows version of supermodel in the operating system and I'm using Proton. For those who know what proton is it's a compatibility layer that allows you to run Windows applications on SteamOS and for the most part I don't have any issues it works really good!!!
Don't need a PS5 or Xbox Series X or S since I built this monster or AKA Mighty Mouse 
. When playing LA Machine Guns in full 1080p, I'm experiencing some frame drops fluctuating during gameplay while the explosions happens. That's because I was running Supermodel in a window instead of 1920x1080 in full screen.
