Ok figured I would just go ahead and try some fab work.
The first thing I had to do was fab some clips to keep main board fastened to bottom of case.
Then fab some stand offs to keep second board from sitting on chip.
As you can see the second board rides high in the case.
The last thing to do is make spacers for case screws and a shield for gap.
All the materials I used were all found at Lowes.
For the brackets I used Mending plate 1/2x5.5x.035 You will have to use heat to bend strap or it will break.
mounting screws are 6/32x3/4. These can be 1/2 in.
nuts are nylon lock nuts 6/32
and new case screws are 8x 1 1/2.
