I have the TT Tsunami. I am using the Vantec 201 fan controllers. The door will not close 100%. I say you need another 5% off space in order to close the door completely.
Here are some additional observations with the TT Tsunami case.
The TT Tsunami is a good case, but it is about 3 inches shorter than a Chieftec mid tower. I believe this 3 inch difference affects the air flow. Thus raising the case and CPU temps by about 2-3 degrees. The positive of this case is it replaces two intake and exhause 80 mm fans with two 120 mm intake and exhause fans. This lowers the noise level noticeably.
Another observation, if I increase the 120 mm fan speeds in the case I don't see any noticeable drops with the temperatures. With the Chieftec mid tower case if I increase the fan speeds of the 80 mm fans I see the case and CPU temps drop 2-3 degrees. I would give up the 2-3 degrees for a lower fan noise any day.
This is just my observation. I could be doing something wrong or that I am not doing a good job with my cable management.
Good Luck with your decision.
