On Figure 7 you can see the top panel, which comes with a 120-mm fan. As mentioned P183’s brother P193 comes with two 140-mm fans here. P183 comes with a fan controller for its two fans, located on the top part from the rear panel.

The other 120-mm fan is located on the rear panel, and on this case the power supply is installed on the bottom part of the case. The slot covers have holes to improve airflow and this case has also two holes protected with rubber covers for you to install external water-cooling solutions.

If you pay close attention to the place where the power supply is installed you will notice that this case comes with a frame to allow standard power supplies to be installed. If you remove this frame you can install bigger power supplies from Antec CP series, like Antec CP-850, which is a power supply that only fits certain cases from Antec, like P183, P193 and Twelve Hundred.

P183 comes with two fan speed controllers, one for each fan. You can set each fan at three different speeds: low, medium and high. Antec doesn’t say how many rpm these speeds actually represent. These controllers use regular peripheral power plugs, so you can’t install them to the motherboard in order to monitor the speed from the fans.
