Specifically the changes made to improve airflow. It certainly changes the aesthetics (form is a feature to some more important than function) and build options with the removal of the drive mounts on the bottom. While airflow is important, 4x120mm fans can push a lot of air and those still concerned about heat have water cooling options...especially if you have money to purchase the bleeding edge hardware which is likely creating this excess heat. I'd like to see a chart showing if the difference the V6 will make in temperatures outweighs the controversy. SFF labs has other products, maybe focus on those and don't fix what ain't broke or just sell the NCase minus the side panels.
However, I do agree with the other changes, specifically making the drive cage more functional and the bottom dust filter/140 fan option.
Customers could be perplexed by releasing a beta version then offering the completed revision at extra cost and time down the road...we get enough of that on the software end these days, a decadence that I hope does not contact hardware. I can't just download a piece of hardware and wake up in the morning with it installed.
If people want a power switch only, no power switch, or whatever, just sell them the blank and they can mod it to their own specs or someone can purchase them and make a little money on the side manufacturing a high quality mod. Put a vandal switch in there, RGB whatever, backlit USB ports or even a switch to toggle boot drive/OS.
