So, I've had my current setup for about 3 years and I've never bothered with cable organization. I've got an 850W PSU with about a million connectors on it and when i built this rig I just kind of ziptied them in a bundle and let them dangle. It looked absolutely terrible:
no doubt it probably impeded airflow too, though the CM Stacker 830 is a really free-flowing case (considering all six sides of it have mesh on them). Regardless, it looked crap.
So I cut the ties, opened the bundle, hid three of the wires behind the PSU itself shoved between the PSU and the mounting rail, ran the molex and SATA power ones that I needed behind the motherboard tray and through a small crack in the frame, and then took the remaining two bundles of wires and ziptied them in to the uppermost 5.25" bay out of the way.
I still need to clip the ties and everything, but for a quick 20 minute job it looks tons better:
all this in preparation to take off the 4-fan-holder-side-panel thing, and take off the mesh from the side panel, and see about making a plexi window for it and throwing some lights in there.

also when I go back in there I plan on changing out the IDE cable for something a little better looking, plus color matching the IDE and both SATA cables so that it doesn't look disorganized. and of course doing a little more cable management. I plan on adding a few LED fans and maybe a dual cathode kit on a rocker switch.
