Pretty intriguing. Those three 120mm fans sound great. I had to mod the side panels of my QPack with mesh replacements and externally mounted fans to get the amount of airflow I was comfortable with. That NZXT case would have great airflow straight out of the box.
The only thing that would give me pause are the comments made by the NZXT company rep, that 1) it's a bit on the heavy side for micro cube case, and 2) it's 20-30% bigger than current cube cases on the market. But that 20% (volume increase?) might not translate to a drastically bigger footprint.
Either way, this might end up being my new case when I finally outgrow my aging QPack and do an upgrade in a few years.
