rsdi has a great post explaining his new controller and how he mounted the 7i92 and power supply in his 1100 panel using DIN rail and standoffs.

With respect I'd be very cautious about mounting switch mode power supplies directly above the machine controller board without EMI screening. At the very least I would have first mounted a metal plate on the standoffs and then mount the din rail onto the plate.
