my bitfenix case has single LED ones, but the LED has a removable jumper and extra cable so you can power the LED directly from a controller board independently of the fan. The case has LED switching etc which at the time I thought gimmicky but actually is jolly handy for tinkering inside the case, and for seeing when the thing is still powered on before you inadvertently touch something that's still live. That's 2010 tech if not earlier
