For cable management, I used StarTech open-slot cable management raceway. There’s a Monoprice under-desk cable tray mounted below the top shelf of the desk. I found a 36” aluminum Tripp Lite twelve-outlet surge protector that happens to match the width of my desk perfectly. And, of course, the aluminum matches the aesthetic. It’s mounted to the back of the desk, with outlets facing down, toward the cable tray. I got a couple sheets of 1/8 inch plywood, finished them and added magnets. They attach to elevator bolts on the back of the desk. They cover the only areas where the cables would otherwise be exposed and are very easy to remove when I occasionally need to work with the cables.
