Wall mounting small electronics stuff really does make a difference.

If I can avoid stacking electronic stuff on a shelf, or not even have a shelf, so much the better. Especially for gear that is not going to change in configuration very often.

I have been known to just poke screws straight into the drywall for equipment mounting, with nary a plastic plug, but a section of wall mounted plywood makes it easier to rejigger locations as needs evolve. I sometimes paint the board wall colour, if the opportunity arises.

Tucking the equipment inside a closet (perhaps with modest ventilatation), I will install an LED lighting strip so I can see what I am looking at when working in there. Which hopefully is not often.
