Duet 2 Wifi ATX Power supply case

I got my new Duet in a few days ago. I printed the case designed by kuhnikuehnast. It looked like it would fit perfect on my CR-10 S5. Once I printed all of the parts I realized it didn't really have a good place to attach to the frame of the printer without interference. I am using a Corsair 750w ATX power supply and realized I could almost sit the case ontop of the power supply and the fan in the power supply would blow right through the case, not only that but the stepper drivers on this boar
