I don't fully understand. What's the design consideration? My biggest problem is actually that the least power hungry CPU (arm) has very little options if you want to run a server with a bit more processing power.

If you mean that Minecraft is not native.. this is Java , so everything runs in the JVM independent of platform.

I might need a Mac Mini as a server and install Linux on it (is that still an option?) like some kind of NUC...
