This is the secret to a true wireless setup. A sturdy, under-desk steel tray holds all your heavy power strips, massive monitor cables, and bulky charger blocks completely out of sight. Mount it to the back of your desk, drop your cables in, and enjoy a perfectly clean floor. 

For the few cables that absolutely must run from your desk down to your PC or the wall, you need to bundle them together. A flexible neoprene sleeve zips around your loose cords, turning a messy handful of wires into one sleek, black tube.
