I've set up half a dozen different home labs over the years but never used anywhere near the compute or disk capacity I had. It was more about learning things, I guess. I laughed when he mentioned the number of cores he has available.
I used to have a large server serving a couple important things.
I was able to put everything on a fanless zotac box with a 2.5" sata SSD, and it has served well for many years. (and QUITE a bit less electricity, even online 24/7)
In my book, that’s a homelab, it's just a small one (an efficient one?...)
