First I must ask why use a shelf? That would be handy for laying coils of cables or my thoughts at least. I wanted to arrange or ROUTE mine and I came up with dowel rods about 4-6 inches long.
I in essence made some short hall tree's from some scrap 1X2. Here is a pic of a notch I tried and decided to replace notch with the dowels.
I have a five foot long rack with five stands behind. All power is on the lowest and 90 deg crossing with as lard a air gap as I could get
All IC's or any cable is on its own hanger no dual nesting.
And I must say I gained several hundred dollars of clarity from the rat nest I had prior.
