We've had our hands on various Silverstone cases in recent times, with the Raven RV03 being one of our favorites. As the latest member of the elite Raven family, the RV03 continued the tradition of using the "stack effect" which mounts the internal components at a 90 degree angle, pointing the "rear" I/O panel upward.Although much of the enthusiast community's attention has been focused on the Raven cases, Silverstone offers a vast array of enclosures that rank favorably among system builders. The company's Fortress series is one such example, comprised of a very diverse range of mid-sized high-end cases that are constructed from a thick aluminum body to create a light yet durable chassis. Silverstone launched its first Fortress series case in late 2008 as the FT01. This mid-tower ATX case was meant to be a gaming solution that primarily focused on efficient cooling. Silverstone achieved great performance by using positive air pressure, i.e. forcing copious volumes of air into the case with dual 180mm fans while having minimal exhaust.
