I'm looking at the Digital Doc fan controller for my system, but had some questions. I've found the older ones on eBay for $29.99, but they have the amber screen and fan (instead of the blue screen and USB/1394 ports). Is there a way to change the screen to a different color? If so, does anyone know where I can get one (preferrably blue)? I really don't care about (or need) the USB/1394 ports, otherwise I'd just buy the newer one with the blue screen. Also, is the 40mm fan in the front one of the 8 that the Digital Doc controls? If so, is there a way I can disconnect it from the controller, and use it normally?
