One of the highlights of this case is the cooling module present on its top panel, featuring two 120 mm fans (1,500 rpm maximum speed). These fans are connected to a switch where you can turn them off or configure them in two different speeds (low and high). Two extra USB ports are available on this module but in order to work they must be connected to regular USB ports located on the rear panel from the motherboard, so basically they are extensions from existing ports, not using motherboard headers.

Finally we have the rear panel in Figure 8. As you can see, the rear panel is painted black, giving this case a very professional looks. The power supply is installed on the bottom part of the case and there is a 120 mm fan on the rear panel (rotating at 1,100 rpm and also using a standard peripheral power connector, so you need to connect it directly on the power supply). R120-V3 has seven expansion slots using solid covers. In Figure 8 you can also see the two USB connectors to be connected on the motherboard rear panel if you want to use the USB ports available on the top panel.
