Where do you buy the case?
Does anyone know where to plug the 12v input molex ? Do u ever need to plug it in at all ?
I suppose the molex you're referring to is for the fan hub right? Try to on your system without the molex connected and see if there's any fans not turning. If not turning means that you do not have enough power so you'll have to connect the molex. Or else just ignore it.
