Before showing you the inside of Raven, take a look at the side panels in Figure 13. They both have dust filters on their air intakes. Unfortunately these filters can’t be easily removed: you need to unscrew them. SilverStone could have added a better system here.

In Figure 14, you can see inside Raven. See how all parts are black, giving a nice look to this case.

As mentioned, this case has a 120 mm fan on the top, rotating at 950 rpm. Daughter boards are fastened to the case using regular screws, and we think for a better appearance SilverStone should have used black thumbscrews.

Raven features two 180 mm fans rotating at 700 rpm, one between the motherboard compartment and the power supply compartment (Figure 15) and another between the hard disk drive cage and the power supply compartment (Figure 16). All fans use a three-pin connector, allowing you to install them directly on the motherboard and thus monitor their speed. No fan speed control is available.

All fans 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. In fact SilverStone posted a very interesting video on YouTube showing how the airflow works on Raven RV01. Another air intake is present on the bottom of the case, featuring a removable washable dust filter.
