Who has installed a LED CPU or case fans this LED does not umbedingt. Who has a side window, all other housing it would make no sense, these LED can obstruct lights instead of LED fan, there is a "power pack" for the 2 light sticks with a cable, which terminates in a slot plate with on / off switch as well a Molex 4 pin connector for power supply, the cable is long enough to get it to wire the R4 the power cord until the rear cable compartment, so the power supply cord is flying so not meaningless rum in the housing, the only drawback the cable of the individual lights could have been a little longer. Installed this was in a fractal R4 Black Pearl Window housing.
