With a fully modular PSU, it seems like it would be easier just to buy a bunch of black 18AWG wire, gold pins, black molex connectors and a nice crimping tool for the pins. That way, you could make/sleeve your own cables with custom lengths. Has anyone done this here?

I ordered my new Seasonic X750 PSU and I am trying to decide if I should mod the existing cables or just build new ones.
