Thanks guys, they made the case a little more versatile, the case allows the option of screwing on the PCB directly into the case if you dont want to use a plate (which is red). I also posted a few photos in another thread showing the blocks that were available to make your keyboard 84 key instead of my current setup. I think a majority of the changes from the kmac 1 and 2 were the aesthetics of the keyboard, I recall some people talking about how the kmac 1 coating began to wore off where there was constant contact with your hands, hopefully the hard anodizing on the kmac 2 will last a longer than its' predecessor.
The color of the case has the same issue as the KMAC LE in that the top half of the case is a different shade than the bottom half of the case, it is minimal, but noticeable. Also for those that are building this yourselves, there is a strip of PCB that is supposed to break off on both the top and the bottom of the PCB. KBDmania left a strip of the PCB under the mini usb which is supposed to be removed but since it is practically attached to the mini USB it is impossible to break off that piece, so what I did was I had to use a file, and file it down until it could be ripped off with tweezers.
I'm currently using MX blues with 65g springs, stickered and lubed.
