Keep cool with the O11 Dynamic series all-new design and express the preferable configuration.











The Lian Li O11D range is known for its modular innovations. The latest O11D EVO takes modularity to the next level. In addition to the easy to remove panels, this mid-tower case can be configured in one of two modes: Normal and Reverse. Whether your desk set-up is skewed to the left or right, you can create the perfect showcase gaming PC. Thanks to the hassle-free design, it only takes a few simple steps to arrange the Lian Li O11D EVO into Reverse Mode. The top and bottom panels can be switched and the whole case flipped, putting your hardware to the left-hand side of the case rather than the traditional right.

Creating complete flexibility, there are five accessories available to purchase separately, which support additional options, two of which are panels for the chassis. Firstly, there is a front mesh panel (O11DE-4X) that can be used in lieu of the tempered glass to maximise airflow. There is also a top panel with integrated I/O panel (O11DE-5X), should you keep your PC tower under the desk and require easy access.

Further supporting the utmost flexibility, there are three places to install the I/O panel. By default, it is placed between the feet on the bottom of the front panel. Alternatively, the I/O can be installed to the front of the left panel or the rear of the right panel (in Reverse mode). What’s more, there is an additional I/O panel accessory (O11DE-3X) that can be mounted to one of the unused areas alongside the standard panel. This provides an extra three USB ports, maximising connectivity.

The final two accessories are PCIe riser cables for alternative orientations for your graphics card.


Thanks to the spacious, dual-chamber interior, the Lian Li O11D EVO PC Case can accommodate for all your gaming hardware in a number of configurations. Able to support up to an E-ATX motherboard, this chassis has 8 expansion slots. With the tempered glass side panel, you can create a truly show-stopping gaming PC.

To start with, this chassis includes an anti-sag bracket and can host a GPU up to 422m long – in one of three positions. In addition to the traditional horizontal configuration, you can install the graphics card vertically or upright. This can be achieved with the vertical (O11DE-1X) and upright (O11DE-2X) PCIe riser cable kits. In the vertical orientation, your GPU can be placed with either a 50mm or 90.5mm clearance from the bottom panel. In either position, there is ample space for AiO water cooling loops. Opting for the upright GPU fully showcases your high-end hardware, as well as maximising airflow.

For holding your extensive gaming library and more, up to nine storage drives can be installed in the Lian Li O11D EVO thanks to the included brackets. You can integrate up to nine SSDs or a combination of six HDDs and three SSDs. This innovative case features mounting points throughout the chassis to create the most comprehensive storage solution. The side drive tray holds either four 2.5” or two 3.5” drives, whilst the cable management bar can host two 2.5” drives, plus a Lian Li and der8auer plaque! These can both be found in the second, smaller chamber behind the main chamber, along with the drive cage. This can hold either three 2.5” drives or two 3.5” and one 2.5” drive, with the option to mount a 60mm fan to enhance cooling. Lastly, the bottom fan bracket can hold four SSDs or two HDDs within the front chamber.

The drive cage and bottom fan bracket do have alternative uses, should nine storage drives be more than you could ever need. The drive cage can double up as a PSU shroud, meaning there is potential for two power supplies to be installed. Models can be up to 220mm in length. Naturally, the bottom fan bracket can be also utilised for your thermal solution, either for fans or a radiator depending on your cooling preference.


Keeping your options open, the Lian Li O11D EVO PC Case is compatible with both air and water cooling. Depending on how you configure certain hardware and panels will dictate the best cooling solution for your build.

If you opt for the front mesh panel and upright GPU, then the Lian Li O11D EVO is going to have phenomenal airflow. With a fine mesh, these panels have been optimised for thermal performance as well acting as dust filters. The upright GPU allows unprecedented and direct airflow to the graphics card and CPU, that can be further boosted by three 120mm fans. Alternatively, the upright GPU placement also allows for amazing customisation for water cooling. Simpler and more efficient tubing can reach hardware without restriction, which in turn helps the radiators to perform more effectively.

Should you prefer vertical or, the more traditional, horizontal mounting, then AiO cooling is the best option. There is support for three radiators and up to ten fans across the chassis. In both Normal and Reverse modes, up to a 360mm radiator can be mounted on the top, side, and bottom, with the latter two having support for 280mm models, also. Depending on radiator size, up to three 120mm or two 140mm fans can be installed in the same areas, with the tenth being a 120mm fan on the rear.


Utilising the innovative, dual-chamber design, cable management is incredibly easy within the Lian Li O11D EVO. There is even a cable management bar as part of the second chamber, allowing you to neatly bundle cables together and feed them through the rubber grommets on the separating panel. This chamber features everything you need to keep cables under control, including a hook and ties. Not only does this design keep your PC interior looking sleek, but keeping the PSU separate helps to keep temperatures down.

Overall, the Lian Li O11D EVO PC Case has a sleek and modern design. The main structure is manufactured with stainless steel whilst the exterior panelling is either brushed aluminium, mesh, or tinted tempered glass. Contributing to the smooth aesthetic, the power button wraps around two edges of the chassis, whilst the reset and RGB buttons remain on the side. This incredible case is available in three colours, with this model being the black version. Inside and out, this PC case has a classic and iconic look.


Completing this versatile case, is an RGB LED strip on the front panel. Simple, yet sophisticated, the Lian Li O11D EVO lighting can be set as one of seven effects, via the “M” button located on the right-side panel. (Or left in Reverse mode.) An eighth lighting mode can be unlocked, via compatible motherboard software or when connected to L-Connect control. This can be achieved with a Lian Li UNI HUB.
