Description
First of all, I am not Handmax Workshop. I saw this on Toms Hardware and printed off the files to build my own.
However, as a lot of other people found, not all ATX PSU's are created equal.
In my build I'm using an ATX Power Supply by FSP, 350W. It's a hair bigger than 150x85mm which is what the ATX standard sets out.
The standard size is included, as well as my enlarged version which keeps the screw holes in the same place.
I intend to add more modifications, like change the USB A port for a USB C, and add holes for fuse holders. But for now this seems like the best place to put the files so more people can access them.

You may have the bits already, or if you hunt around you can get them cheaper. These are just parts I know will fit.
