The side panels are screwed to the chassis using silver thumbscrews. SilverStone could have added a better system here or at least shipped this case with black thumbscrews. All internal parts are painted black, giving a really good looks to the case.

What immediately caught our attention were the three enormous 180 mm fans (speed varying between 700 rpm and 1,000 rpm, noise level varying between 18 dBA and 27 dBA, depending on how you set the switch available on the top panel) located at the bottom of the case, each one featuring individual and easy to remove dust filters. Each fan is connected to an individual speed controller (see Figure 9) and they all blow air from the bottom part of the case to the top. Since there is more air being pushed inside the motherboard compartment than being pulled out of it, this case is said to be based on a positive air pressure design.

Raven RV02 has two holes for you to pass hoses from water cooling systems located on the bottom part of the case, between the rear panel and the fan, as you can see in Figure 13.
