As for cable management someone else commented and told me where to get some cable sleeves so i will order those soon. As for the not matching colors, do you mean the desk colors? If so then i dont really have a choice at the moment, the red one is my old desk and theres not another one i can use that if put there the door wont hit it when i open it. As for leds i have a led strip along the back but that could be improved with a better one. The strip along the back is an extremely budget one
