Dude the Atari VCS. It's basically a steam deck in a different box (very similar AMD SoCs), but you can get the VCS for less than an RP4 -- like $120 on sale. They were down to $99 for a minute but I don't think they'll go that low again. And this thing is great. You can boot it from an external SSD with something like Batocera for emulation, and it is a beast. I haven't found a system on Batocera that doesn't go full spead on the VCS, and I'll throw some dumb shaders on shit just because. I've got another SSD with ChimeraOS for all my Steam games, and everything runs perfectly as long as you use whichever settings would be appropriate for the Steam deck. And -- and -- the built in AtariOS and its associated games are surprisingly good. That's just a bonus, although the games that the kids and I play together mainly live there (the Recharged! series of games like Asteroids, Centipede, etc.) We've got three VCSs now: one upstairs (our game room), one downstairs (the kids game room), and one in our office that my wife uses for streaming (although I added 32 GB or RAM to that one). As a single-board computer it's at a price/performance sweet spot that is very, very hard to beat. More on reddit.com

The only annoying thing about the Zero 2W is that it still uses a micro-USB port instead of USB-C. More on reddit.com

You can run Windows for ARM on the Raspberry Pi 4. If you want one that runs x86-64 Windows, the LattePanda is the one I've heard others talk about. https://www.lattepanda.com/ More on reddit.com
