Not a bad looking case but it can't match the Tempest in terms of cooling performance. There's not enough info about this. For example what size is it classified and what are the maximum number of fans it can hold (apart from the preinstalled 3 which is lowly by today's standards).
This is sent to me by email there was no information on the NZXT site at the time of the post. More info at the link here Unix and its priced 20-30USD less than the Tempest so don't think they are really comparing the two NZXT. Products.
The tempest sells for 99$, for 10$ more you'd be getting one of the best midi cases in terms of airflow and capacity. My case is the thermaltake armor (as seen in sig pic) but I would have easily gone for the tempest if it was available where I live.
I know we will be covering more on the Tempest soon Bro If the information on the maximum number of fans in the link wasn't enough let me know and I will email Johnny Hou for you.
