Hardware
Main Server is Refurbished Dell Optiplex 9020. Addional Compute provided by custom built PC for AI/ML tasks. 1 RPI4, and 1 RPI Pico 2W for small tasks and messing around. Last 1 Refurbished Dell Optiplex 790 used for Linux and Contained Red Hat Blue Hat hacking. Looking to expand into radio technology and making a LoRa mesh for my devices.
Software
TrueNasSCALE is main server. On top of that then I built custom docker web app (node), but I have used Appache and Webdav Before. I also use a TailScale VPN to mesh all of my devices. Additionally a cusomt MQTT server and a Python Server (streamlit/flask for web, rest is custom) both run on top of the SCALE. Other than that I have PI hole and use Postgres.
