CachyOS would require Arch Linux to implement the support first. Progress is slow but steady:

- https://rfc.archlinux.page/0032-arch-linux-ports/

Adding onto this, progress is moving faster thanks to Valve contributing to efforts such as buildbtw for arch.

Not out of the goodness of valve's heart either, they want it for arm based steamOS devices like the frame. A win win for many though.

I'm curious, what hardware would you run it on?

I oftentimes run Linux Desktop fullscreen in a VM on macOS. macOS acts like a hardware abstraction layer in that case. Depending on the task and the tools, I sometimes prefer this option (I do like the macOS UI though (except for the current version), I just like to use the right tool for the job)

M2 Ultra Mac Pro with 192GB RAM?
