I run a home-server with pretty high spec and how much extra juice it has left over has been bothering me. It feels wasteful. My server isn't bound by CPU almost at all - the most intensive thing is the occasional trans-coding for jellyfin, however it does use quite a bit of ram for a couple of minecraft servers and ZFS. I'd really like some sort of preferably arm or maybe risc-v based server (in the future) that can take sata and a good bit of ram but most of the SBCs I see would require that my drives work over USB which is annoying and usually dont have more than 4/8gb of ram.
