This is the correct answer.
I built my own a decade ago, it was boss in that it fitted perfectly into the space, was the correct height, so no bad back, had doors and a lid, so no dust collecting on everything and no having to look at a bunch of wires all the time.
Had mine on wheels too… this was ill thought out though, as it was fuckin large and held over 800 pieces of vinyl, meaning it needed a rugby team to wheel it around.
Would defo go with a lid of some sort if you can, it just makes it more useable, stops you having to dust, and you don’t have to look at them all the time.
