The side panel of the X-Blade adds to the aggressive look of the front bezel, or vice-versa. As you can see, this isn't your standard run of the mill windowed side panel. The window of the side panel is cut out in the same design as the chrome trim on the door of the case front, as well as that here on the intake fan. Centered in the design is the same raised black mesh trimmed out in chrome that is on the front. But here, it conceals an 80mm LED intake fan.
