I would like to start with saying it's huge! It does look good, especially if you like those prominent ribs at the top/front/back of the case. However, there are a few quirks, which may prevent you from calling it the perfect case, despite the price.
First, I have experienced a problem with 1600W power supply. The case intake opening blocks about 2/3rds of the PSU air intake. Tech support did not have any suggestions. Another possibly is to install the PSU with the intake up, in which case, it would be sucking int warm air and a good portion (at least 50%) of the intake would still be blocked.
Installing two large radiators could be also a problem. For example, the space on the top will let you install one 280mm radiator, for CLC thus if you have another large radiator for VGA cooling, you would have a hard time deciding on its location. The back door does have space, but does not have proper mounting options.
A small annoyance is the temp sensor. Why not have two or three for a case this big? The cable for my sensor was also not big enough to reach where I needed it. A also did not like that it takes a long time for the sensor to change its temperature in response to changing case temperature.
If I knew about all these problems, I would have just settled for the open-air build. The only disadvantage of the open-air build I is possibly the dust management; having to blow dust/vacuum components more often vs cleaning intake filters.
That said, the case feels spacious, and my VGA temps dropped comparing to a smaller case I had before.
