Well done! Love the use of a two post rack. What wire management do you have on the side of the rack?
That is Telect "Links" - used in carrier grade telecom offices for fiber cables. I had a bunch left over from my telecom install days, and used it as vertical cable management on that rack as well as under the desk. If you possibly notice in a couple pictures, under the desk the same red fiber tray is under there. That hides all the MANY wires to my monitors, phone, keyboard, mouse, headset, etc - tons of wires are hidden up and under the back of my desk by the same cable management. Obviously I painted them all red as well from the Telect yellow.
Here is what they are:
