I actually have the 680x with 8 LL120's installed in mine and for what i needed was 2 lighting nodes and 1 commander pro. the case should come with 1 lighting node and when i bought a 3 pack of ll120s a lighting node also came with it and then i just bought the commander pro. just plug in all the rgb lighting fan cables to the 2 nodes and all the pwm connectors to the commander pro and it should be good to go on icue hope this helps
