It's funny how the term has come to mean "overkill home servers" now, and the lab part has gone somewhat missing or at least isn't a core part anymore. A lab is traditionally where you experiment and try stuff you want to understand, not something you use to run your home network. E.g. for network folks going for vendor certifications often a big pile of outdated (=cheap) networking hardware to get hands-on experience. Or if you want to learn Kubernetes or try a specific configuration and set that up on some servers. I don't really have one, experimental/learning stuff is done either on my normal PCs or on VPSes. I have a small home server, which just runs filesharing and some tiny services.
