The two-chamber design of the O11Dynamic XL is the main element for its appearance. The two tempered glass windows on the left side and front are particularly striking. These offer a perfect view of the inside of the case.
An RGB LED strip separates the front glass from the aluminium cover of the second chamber. Here is also the I/O panel. There you can find the power and reset switch, two USB 3.0 type A and one USB 3.1 type C connectors, one audio input and output each, as well as two switches for operating the RGB lighting. This allows all colors and effects of the integrated RGB controller and thus of the LED strip on the front panel to be switched through. Two additional USB 3.0 type A connectors are installed in the front foot of the housing.
On the upper side there are ventilation slots which serve as outlets or inlets for fans or radiators. Just like on the right panel. One can therefore assume that the case has excellent airflow characteristics.
The back has eight expansion slots for e.g. graphics or sound cards. In addition, there are two vertical slots.
There is also a removable dust filter on the underside.
