I built a pretty serious "homelab" over a few years, in the sense of building out 24/7 services as robustly as possible. There is an element of practicality for very long-term maintenance if you run i.e. VMs off a different storage layer. But mostly? It felt exactly like exploring computers in my childhood for the first time (I'm 43 now). I was bumping into things I had never bumped into it before, and it was really satisfying to figure all that stuff out. I'm a game developer, too, and I realized awhile ago a big part of that is I like technical puzzles, and game development is very fertile soil. But there is a whole new world of enterprise networking/storage/virtualization/etc things that you wouldn't normally bump into in the course of software development. And as a bonus, I have set up a lot of build systems for friends; being infrastructure-savvy is like the digital equivalent of owning a truck and helping people move all the time.
