Let's see.

• A meda stack (plex/jellyfin, sonarr/radarr, sabnzb, etc).
• an instance of foundryvtt
• a local mirror of 5e.tools
• a "tilt pi" ( Bluetooth hydrometer that supports webhooks/apis)
• ad (I need to decom this and just use aad)
• some raspberry pi's running octoprint.
• pihole.
• "general networking stuff" (wire guard, openvpn, network monitoring, etc)
• nginx as a reverse proxy.

I'm sure I'm missing stuff but that's a basic list.

Interesting fact: I just got a new ev (so a battery hooked up to a computer with wheels) - and it has buttons! It also has dials for sound and climate.

Now to be fair it also takes interacting with a touchscreen to turn on the heated seats, but I'd say it's progress in the right direction.
