The wishlist name can't be left blank

PC case lighting hubs allow you to run multiple lighting examples from a single power or control source. Custom PC lighting often involves multiple light sources to place the lighting where the user needs it. Rather than running separate power and control wiring from the source to each light, hubs are used. Power or a control signal or both are fed to the hub from the PC. Each light is then routed to the hub. In this way, multiple lights can be powered and controlled simultaneously with a minimum of wiring.
