The pc does not have back compartment, nor anyway to attack the cable to. What I am thinking right now is to hot glue some zip ties to the centre gap between HDD and mb. And then zip ties the cable to the zip tie, so it runs down the centre of the pc cleanly and branches out to its destination like a upside-down tree.
Yes, but only people who are super OCD about cable management would spend the time. I have a buddy who’s really good at cable management. You could bring your computer to California and maybe he’ll do it for you if you buy him lunch.
