Considering all the virtualization experiments you can run on them, home server platforms tend to require somewhat decent systems. But then you have tools like Proxmox that can run on potato hardware despite offering killer features. In fact, I’ve deployed PVE on several dinosaur machines, and it has served my needs pretty well. However, aside from an LXC-hosting decade-old laptop (and that one time I tried running a Hackintosh on an SBC), I often end up clustering low-power devices with a somewhat capable system for a high-availability setup.
