Silverstone Raven EATX Tower Case
 

Silverstone cases are usually well-constructed with good fundamentals and dispense with frivolous aesthetics and features. The Raven is perhaps their first departure from this course and it is certainly a dramatic one. Not only is the outside radically different from anything they've done before, the motherboard tray has been rotated 90 degrees clockwise.
