In Figure 13, you can see the place where the power supply is installed. There are two wheels to allow you to easily slide the power supply into the case. If you have a power supply with a 120 mm or bigger fan on its bottom part, you need to install it with its fan facing down. In this case you should install the stands that come with the case, so air can flow to the power supply fan. You can also install a fan below the power supply stand, if you want to.

Right next to the power supply compartment there is space for installing a 120 mm fan, shown in Figure 14. There is also another space for installing another 120 mm fan right below the lower hard disk drive cage, but in order to use it you have to remove the bottom hard drive cage, which is really complicated to do (we will explain in details how this can be done).

In Figure 15, you can see the rear and top 120 mm fans (no word on speed, airflow or noise level). These are the only fans that come with the product. They use a three-pin connector, so you can install them directly on the motherboard in order to monitor their speed. You can, however, use an adapter that comes with the product (ZM-MC1) to select between two voltages, +12 V (black connectors, full speed) or +5 V (white connectors, a little bit less than half the speed). There is space for installing another 120 mm fan on the top part of the case.
