Optiplex 9020's make surprisingly good home servers. I have three, a 2 node proxmox cluster and 1 running as a NAS. The cluster is running 15 VM's including a 5 node docker swarm. I downsized from older HP G1 series in a rack when I moved across country in 2019 and couldn't be happier. Runs everything I need and they were cheap to max out.
