I currently brought a 680x because it's such a beautiful case. I plan on adding 5 more LL fans, Two LL140mm on the top, Two LLLL on the bottom and 1 LL140mm on the back. Including the 3 120 fans, this comes to a total of 8 fans however the fan hub only has 6 and I am confused on how to add the other 2. I have: 3 x LL120 5 x LL140 3 x RGB LED Lighting PRO 2 x Lighting Node Pro 1 x RGB Fan Hub 1 x Commander Pro Thanks for the help, planning to build this beauty soon.
