I recommend split loom, like what they use in cars around wire looms. It is a plastic tubing with ribs so it can stretch/bend and has a slit down the side to put wires in it. that usually makes the mess look like one big thick wire and looks a thousand times better and it looks professional rather then a piece of cloth that you can still see the wires with which looks like a jimmy-rigged setup. I would do 2 looms, 1 power, and 1 for your cables. The mess at the bottom can be looped back up if you do it right without pinching/kinking them.
