Hiya Cesar cheers for the reply, i'm well used to the jerks now, i'm immune to them, lol. The coolmod is basically the ability to attach that purple light thing on top of the fan, so that it takes the place of the yellow hard-disk activity LED on the front of the case. So every time your hard-drive does anything the light on the fan is activated instead. I'm just not sure if it means that it renders the hard-disk LED on the front of the case useless or not. :beer:
