Something I always found interesting was a cyberdeck which is kind of like a mishmash of components. Nowadays you can use sbcs for the hardware but I’ve always been given the families ewaste and doing some research you can reuse a lot of it. I have an old celeron laptop that’s too slow for anything useful. It’s just the bare board now ziptied to the lid of a shoebox and I use it for low power learning server. But found out the display connector it uses for the screen, which is gone, is very common and found a 9 inch screen that would work with it. With a 3d printer you can build cases for everything.
I actually never had an issue on my wayland system. I used remmina for rdp but never had an issue.
