There are some other things floating around in my homelab that aren't really 'selfhosted' things, just important to the home network:
3 HP Microserver Gen8's
-x1 with ESXi hosting pfSense
-x2 with TrueNas Scale for backups
R610 with ESXi for a few remote desktops and Home Assistant (which I'm sure I'll move to docker at some point).
