I got
- A RAID NAS for general
- A Firefly-iii instance for expense analysis and stuff
- And MQTT broker for my ESP32 projects
- A webdav server for calendar and address book syncing and general file syncing for some things like joplin
There are probably other things that I don't remember right now.
In terms of hardware I got a 6 core AMD 5600X machine with a 5700XT GPU and 16GB of ram for almost all my services and personal use.
I also have an AMD 3600 machine with 3x8TB harddrives for network storage.
