TFX PSU (small form factor) mounting brackets

Brackets for mounting TFX power supply on a flat surface. TFX PSUs are typically found in SFF (small form factor) PCs. See dimensions of all sorts of PC PSUs here:

I designed the brackets with holes that will fit M4 screws on the mounting side. I wanted to mount my PSU to a wooden cabinet, so I used 4 "Hex Screw Insert Nut" (ebay keywords) screwed in the wood panel.
