My funky Eurorack

Could I, in theory, use three moog 60hp cases and cut holes between them to distribute power with the microZeus?

Technically yes.. But you´d need some big decent big drill to pass your flying power bus through that hole. Also you´ll still need some stand to stack the cases if you want to put those one over the other... And, if you eventually wanna sell your 60hp´s, a drilled item should rest value... Would definitely think in a built in case here... similar cost, less effort. http://store.synthrotek.com/Eurorack_Enclosures
