> It's slightly more cost-effective and usually more power-efficient to build or buy a small NUC ("Next Unit of Computing") machine that has more raw CPU performance, more RAM, a fast SSD, and more expansion capabilities.
But is building some VMs to simulate a cluster on an NUC fun?
I would say, "No." Well, not as much as building a cluster of Raspberry Pis!

You don’t build a RPi cluster for speed or cost or efficiency. You do it because it’s fun. And that’s okay.
