Home lab notes: small boxes, quiet fans
Most of what I run at home fits on a single mini PC with 32 GB of RAM: a media server, a few containers for experiments, backups and a small Git mirror. The rack I planned two years ago never happened, and I don't miss it.
Rules I ended up with: everything is rebuilt from a script, nothing important lives only on one disk, and anything that needs a GPU runs on the desktop instead of the server. The quietest fan is the one you never install.
