The Top Panel
The top panel of the Corsair 600T can be seen in Figure 6. It features a 200 mm fan identical to the one available on the front panel. By pushing the top panel mesh you release it (it uses a mechanism identical to the one used on the front panel, where you have to push instead of pull, which works great). This mesh hides a lock for the left-side panel of the case.
The 600T comes with four USB 2.0 ports, one USB 3.0 port, one FireWire port, and the audio jacks on its top panel. A big knob for controlling the speed of the fans is also available. This controller can handle up to four fans, so you can control all three fans with it. Just keep in mind that, since this controller has only one knob, all fans will spin at the same speed.
