I'm running a similar setup, but with k3s on Raspberry Pis and an old Mac Mini. For me it's about running home automation workloads (that should stay in the LAN) as well as learning and experimenting with devops tooling, currently working on managing everything with Ansible as well, still not sure whether to use a k3s role from Ansible Galaxy or just k3sup (anyone got a recommendation?) and running one of the k3s nodes on a Raspberry Pi robot I was gifted for Christmas, mainly because I can. If I did the same on AWS I'd pay a big lot more and that'd cut into budgets for other pastimes. Also I wouldn't get to tinker with hardware and do some of the more exotic things like exposing GPIO pins to Kubernetes workloads, and if I ran home automation workloads there, they'd be useless if my uplink fails. But if this was work, I'd do things differently for sure.
