I have a ten-year old MacBook Pro with an i7 and 16gb of ram. Just because this thing was a total beast when it was new does not mean it isn’t old now. works great with Ubuntu though. It’s still not a good idea to run it as a server though. My raspberry pi consumes a lot less energy for some basic web hosting tasks. I only use the old MBP to run memory intense docker containers like openrouteservice and I guess just using some hosting service for that would not be much more expensive.
