Most of my compute is very low-powered, I have been following the Tiny-Mini-Micro trend to build some low-cost, low-powered compute. There are times however, when you need some more oomph for single-threaded applications or high-speed storage. For this I have a separate AM4 based node. This is a whitebox based around the AsRock x470D4U so I still get IPMI.
I run publicly accessible game servers for my friends, I trust these game servers about as far as they can throw me so each game has it's own vlan with firewall rules preventing it from reaching anything.
