It's indescriptible how much a good case helps with cable management. I've never bothered with it, but after getting a new case and an AIO cooler, I decided it's time to give it a shot and boy, was it trivial. Looks awesome as well. Love the black/purple/white look. I need to get an RGB strip for my desk and the case, perhaps behind the monitor as well, and get them all in some white/light pink/purple fade/gradient kind of thing. Damn that'll look awesome.
Desk cable management = irrelevant, can't see it when looking at the screen anyway, waste of time
