The YY-5601 from Yeong Yang.

Yeong Yang deserves big kudos for sending us the most unique looking case in this review. The YY-5601 provided our first look a truly innovative ventilation system; the front of the case resembles wide louvered blinds that open and close for ventilation adjustment. It's such a simple concept that it makes us wonder why no one thought of it previously - most likely it is because one does not expect to find louvers on the front of a computer case. The YY-5601 was also the only case that featured some new things we have never seen before, and we were most eager to learn about them. Yeong Yang refers to the YY-5601 as "The Cetus." We will be interested to see if this manufacturer can keep up with some of the other reviewed cases.
