Is there so much need to use VMs? Unless you plan to keep Windows or some exotic isolated desktop stuff I think there is a little value from using VMs. LXC/Docker/Jails should satisfy most of self-hosting homelab needs. I got 4 bay Synology NAS with Intel CPU & 8GB RAM which nicely runs Docker, some reddit users boost it even up to 16 and 32GB RAM. Plus OpenWRT router. Entire "rig" eats like 40Watts.
