Ok I'm completely new to building PCs. I am about to build my very first computer and I wanted to order all of the parts that I will need. So my question is, does all the cabling and wiring come with all the components or is there a kit or something I need to buy? Everything I find literally just says: Case, Power supply, CPU, Cooler, GPU, storage, ram. I don't see anything about wiring. Please help.
