Silverstone's Raven RV01 caught our attention back in 2008 with a unique chassis layout that turned the motherboard upward so its I/O panel was on top of the enclosure instead of behind. Called the "stack effect," the design was highly original and more importantly, extremely effective for cooling. 2014's RV05 sticks to this layout but Silverstone claims to have eliminated much of the wasted space in previous models while bringing one of its better looking designs so far.
