I have three separate servers at home, and while I was in the process of a migration, I had four servers in operation. All three of them are running Proxmox, though not as a cluster. That fourth server I used was a TrueNAS Scale machine that served as my introduction to home labbing, and that introductory piece now lives as a VM on one of my machines. Throughout it all, one piece of hardware has proved invaluable: my portable monitor.
