Raijintek Thetis @ techPowerUp
 

The Raijintek Thetis is a larger version of the Metis, allowing you to use a full-size ATX board, PSU, a fairly long GPU, and even a 240 mm radiator. While all that may not sound interesting on paper, considering the compact size of the Thetis, we are eager to take a look.
