When designing my place (inside a steel building), I built this wall about 2 feet thick. Then framed out these cubbies with a sliding shelf for each piece of equipment. Finished the front with brushed aluminum I made up from flat stock.
I Just thought you might like to see a different type of setup.
I probably should have included an equipment list, sorry…
