The only drawback with the CM 690 is that is doesn't have front USB or audio.
It is contained all on the top front so as to leave the front panel uninhibited. The CM Centurion and Gladiator Range have the front USB/Audio connections but are very basic in comparison for not a whole lot less.
I like what the 690 II can do inside, thinking in the box as they say. The same practicality that is seen in high end Chassis.
