This case doesn’t use a screwless mechanism to fasten daughter boards to the case, but on the other hand it provides thumbscrews, allowing fastening cards without the need of using tools anyway. In fact we personally prefer this approach, as we’ve seen countless times these screwless mechanisms breaking because they are usually manufactured using cheap plastic. On Figure 10 you can also see the rear fan. As mentioned all fans use a small three-pin motherboard connector, but they also come with a standard 4-pin peripheral power plug, to be used if your motherboard doesn’t have enough connectors for all fans.

This case also provides a place in the middle for installing up to three extra 120-mm fans, which don’t come with the product.

On this case the motherboard tray has hinges, facilitating the motherboard installation process. This tray, however, keeps attached to the case. To move the tray you need to remove four screws present on the rear panel (two normal screws and two thumbscrews).
