As commented, this case comes with a 120 mm attached to its side panel, which glows blue when turned on. All fans come with two power connectors: one three-pin to be installed on the motherboard, allowing you to monitor the fan speed through your favorite monitoring program, and one standard peripheral power connector, to be used if your motherboard doesn’t have enough fan power connectors for all fans. We don’t think that there is any motherboard on the market with six fan power connectors, so you will have to choose which fans you want to monitor and connect them to the motherboard, while connecting the remaining fans directly to the power supply. None of the fans provide speed control, so if this case’s noise level disturbs you will need to disconnect one or more fans.
In Figure 8, you can see the case with its left panel removed. The right panel can also be removed, but the motherboard tray is permanently attached to the chassis.
In Figure 9 you see the rear 120 mm fan and the expansion slots. As you can see, no screwless mechanism is used to fasten the daughterboards to the case. You can also see on the right side of this picture the power cables from the two top fans.
In Figure 10, you can see the top panel from the case, with its two 140 mm fans. You can install the radiator of water cooling systems that use two 120 mm fans there. According to NZXT the available holes are compatible with Swiftech MCR220, Asetek Dual radiator solution and Thermaltake TMG2.
