I have to concur with this because the whole idea of a "pi" based homelab is just too anemic for my purposes, when you can spend as little as 200 bucks and get some older x86-64 quad core, 32GB RAM desktop PC from a Dell enterprise series of midtower desktops, which will serve as a much more powerful hypervisor. Spend just a little bit more and you're looking at Dell Precision systems with 64 or 128GB of RAM.
