Controller Board questions

[JurisHP]

I just got a Marine Depot controller board. How do I mount my controllers? Velcro? Something else? Also, I’m thinking of drilling a hole into my cabinet on the side, mounting the controller board on that side and using the hole to put the wires through. Is this a bad idea? Will it weaken the cabinet? I think I know the answer, but.....

How u hang them is just esthetics and up to your preference.
And u should be fine with a 2 " hole for wires.
