Lian Li’s Double Chamber Case under Test: The O11Dynamic XL ROG Certified

The Lian Li O11Dynamic XL Dual-Chamber-Midi-Tower case is the big brother of the O11D Dynamics and has again been developed in cooperation with overclocking legend der8auer. Even if the comparison is a little bit limp, because it is actually a consequent further development. Especially striking is the much larger space and the RGB lighting integrated in the front.

Packaging and Scope of Delivery

The O11Dynamic XL ROG Certified by Lian Li comes in a sturdy cardboard box with black print. The case is protected against shocks with hard foam.

The mounting accessories are contained in a small cardboard box that is inserted in the drive bays accessible from behind. These include various screws for the installation of SSDs and hard disks, as well as Velcro cable ties for perfect cable management.

Since the Dynamic XL was specially designed for water cooling, no fans are included in the scope of delivery. These would not be used as much as possible, as every custom water cooling system has its own requirements. Magnetic mesh dust filters are attached to the air inlets and outlets on the base, lid and right side.


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.

The Interior

Like its predecessors, the Lian Li O11Dynamic XL has two separate chambers. The interior is easily accessible after removing the top cover. Then all side walls and the tempered glass panes can be easily lifted out. Only the rear panel cannot be removed.

In the right chamber all drives, the power supply and the cables are placed. The four 2.5/3.5 inch drive bays, which can be removed individually and are hot-swappable, are accessible from the rear. The drive bays can also be removed and replaced with ATX power supplies if necessary. Three 2.5-inch drives can also be placed on the removable carriage to the right of the mainboard tray. But these can also be removed to mount another 120mm fan or a maximum 360mm radiator. Another three 2.5-inch drives have space behind the mainboard tray on an extra strut. There are enough ventilation slots on the outside at all places that need a good air supply or exhaust air.

E-ATX, ATX, Micro-ATX and Mini-ITX mainboards fit into the case. SSI EEB mainboards can even be installed with an optional expansion board.

According to Lian Li, up to three 120mm or two 140mm fans can be mounted in the base, lid and between the two chambers. Accordingly, radiators up to 360 mm in size and up to 65 mm in height also fit here. An additional 120 mm fan can also be mounted on the rear side above the expansion slots for the PCIe cards. The fact that three fully-fledged radiators can be accommodated here at the same time is the decisive advantage over the predecessor of the O11Dynamic XL ROG Certified. This finally makes it the perfect water cooling housing.

For the digitally addressable control of the lighting, Lian Li has given the case its own RGB LED controller. This either controls the RGB strip itself using the two buttons on the I/O panel, or can loop the signal through directly from a mainboard. This requires a 3-pin D5VG connector (xx_x).

System Construction in the Lian Li O11Dynamic XL

The system is built using an Intel i7 6700K on your Gigabyte Z270 Ultra Gaming and 16GB of memory. The cooling of the 4.2 GHz clocked processor is done by a 360-mm-AiO water cooling from SilentiumPC. The image output is provided by an NVIDIA GeForce GTX 980 Ti in reference design, which is also cooled by an all-in-one water cooling system. The whole system is powered by a 750 Watt Thermaltake power supply. A sleeved CableMod cable extension set in white-black provides a more beautiful look.

Thanks to the spacious interior, the installation of all components was completed quickly. The pre-installed spacers for the mainboard were practical, shortening the working time. The abundant cable management openings ultimately ensure a tidy interior.

The Airflow concept also proved successful in the long-term load test. Even after several hours of intensive gambling with hardware-hungry games, all temperatures were in a pleasantly low range.

Conclusion on the Lian Li O11Dynamic XL ROG Certified

With its two tempered glass panes on the front and left, the O11Dynamic XL is clearly a case that shows what you have. The RGB LED strip in the front makes it even more of an eye-catcher. Lian Li and Roman “der8auer” Hartung outdid themselves. It can’t get any nobler.

But not only the appearance could convince us in the test. Also the Airflow performed surprisingly well. And the space available for water cooling components and other hardware is impressive.

Maybe it’s the most powerful case of 2019 and an absolute must for water cooling enthusiasts!
