As far as I could tell, the best Mac compute power for the money is a Mac Mini from the previous generation (or the one before it) since they had 4-core i7 CPUs back then (the more recent ones only have 2-core CPUs and often i5s unless you spend lots of money).

Thanks. If that’s feasible and works for the guys maintaining the hardware at the farm then I wonder: do we have an estimate how many machines would make an impact or should we try adding a bunch more? Or just wait for yours to arrive?

How much did you pay for the mac mini you managed to get?
