Here is 1 more option for you with the Scythe Kaze Sever model Amazon.com: Scythe Kaze Server 5.25" 4 Channel Fan Controller / Temp Display - Black (KS01-BK): Electronics
I just put one in my Corsair Carbide 400R and the LED color matches perfect to the stock Corsair LED colors. I'm not sure if the White addition 600T has white colored fans but my original 600T does. The best feature with the Scythe is you can turn the display off but still have control of the fans. Here it is in my 400R.
