External Box for PS01 Power Supply

[kid]

I want to house my PS01 that powers 4 N72's into an external box. I plan to move the 4 N72's into another chassis with a PS02 2 A12's and 2 J99's. Instead of modifying the N72 boards as Tim had suggested many years ago by cutting the traces and using a zener to drop the voltage from 27V to 24V. I don't feel confident in performing this procedure and risk destroying my N72's. My hope would be to take the PS01 house it in an external box and run a cable from there into a small Lemo style plug into the PS02 chassis. Can someone recommend an appropriate blank box that would fit the PS01?
