Hardware Secrets posted a review on the SilverStone Raven RV01 Case

Raven from SilverStone (also known as RV01) is a full-tower case with a unique design, where the motherboard is rotated 90º, making the rear connectors to be available on the top part of the case. This was done to improve thermal dissipation, especially from the video card, as hot air tends to go up and high-end video cards usually blow hot air from the inside to the outside of the case – usually to the rear of the case, but with Raven hot air is blown to the top.
