How to insert an ATX PSU into a Supermicro SC842 case?

Question

Iron

There is a Supermicro SuperChassis 842TQ-665B case supermicro.com
There is also a regular CoolerMaster v750 PSU coolermaster.com
The standard PSU mounts in the case are specific and are located inside, the ATX PSU is usually attached to the outer frame of the case with 4 screws, but in the Supermicro case there is no frame with holes for BP.
But I saw frames in other server cases that were attached to the case and the power supply unit was screwed to this frame. On the SC842 to the right (closer to the outputs of the motherboard) there are two holes, probably for this frame.
From here the question is, has anyone encountered such a problem? What is the name of this frame to buy it? Or do you have to cut it yourself?

Answer 1

Since it was necessary to install such PSUs in cases in the amount of more than 50 pieces, we decided to produce an adapter frame.
As a solution, I am enclosing this very drawing, ABC plastic 2 mm thick was used as the material on the prototype, it has sufficient strength characteristics, steel st3 was used as the final product, in which the safety margin already exceeds the necessary ones.
