My Node, Start9 on Purism Mini, Samurai Dojo on a dedicated Thinkpad and starting to try Nix. MyNode and Start9 brilliant so far. Migrating from using Pi's to actual computers from good sources like purism, Sys76, starlabs and trying running Coreboot orsimilair rather than stock firmware. Taken ages to learn but getting better thanks to these great suppliers and coders.
