I have a Raspberry Pi that runs pihole and Wireguard exclusively. My home server is a Kubernetes cluster running on an old desktop PC and 2 Intel NUCs.
The reason for the separate Pi was essentially because I only had the desktop PC initially, and for a while I had a faulty CPU, making the desktop PC crash or become unresponsive, so it helped a lot having DNS and VPN access separated from the instability.
