On Figure 8 you can see Mercury Pro rear panel. As you can see, it comes with two 120 mm fans on its rear (which glow blue when turned on) and it has seven expansion slots. You can also see that there are two holes for hoses, so you will be able to add external water cooling devices. If you want to install a power supply that is longer than normal (e.g. Enermax Galaxy 1,000 W) part of the unit will be left outside the case, and this case comes with a frame to correctly fasten this type of power supply to the case.

As you already know, this case has four 5 ¼” bays, two 3 ½” bays and five internal 3 ½” bays. As you can see on Figure 10, these internal bays are 90º rotate compared to traditional cases, making it easier to install hard disk drives on this product.

On Mercury Pro there is a tool box installed on two of the internal bays (see Figure 11), so if you want to use more than three bays you will need to remove this box.
