Whilst trying to make some room on the testing shelf and tidy up the shelf, I noticed the 350W PSU's had 4 x 4mm threaded holes on the flat side opposite the fan, ideal for mounting under shelf.
Over to tinkercad, a simple 140mm wide peice with a couple holes, recessed screw heads for the M4's and thick enough so the 10mm long ones i had on hand didn't short anything inside.
I'll let some images say the rest.
