Summary: The SilverStone Raven RV01 Case is available in a black color with or without a window. It has a reinforced plastic outer shell & an .8mm steel body. It has a number of very unique features, one of them being that the motherboard tray is rotated 90 degrees clockwise. So instead of having the motherboard's I/O shield plate and expansion slots at the back of the case they are at the top. This frees up the back of the case for things such as a large radiator.
Conclusion: It’s a rare thing when you see a case designer try something truly original, much less succeed. Silverstone has done just that with the Raven, as their re-oriented motherboard arrangement works great to provide excellent cooling and functionality. Tower coolers especially will benefit from the Raven’s unique design, as cool air is forced through the fins thanks to the stacking effect.
