The title's the question. I want to be able to turn the black cables from my PSU into red ones cheaply. Is there a way of covering them in something like red tape or is there another way to do these kind of things, if any.
Will I have to buy cable extensions for every port in the motherboard? I don't have anything in the PCI slots
You won't have to get them for the PCI slots, but I would recommend it when and if you get a graphics card, for the power. They pretty much have extenders for every port you might need, but I would start with the CPU power cable and the 24 pin power cable.
