Pros
- Removable front support pillar provides an uninterrupted view of internal components.
- Supports up to a 420mm radiator on top and 360mm radiators on the side and bottom.
- Features two 1.5mm L-shaped ARGB strips with 14 lighting effects and motherboard sync.
- Accommodates large graphics cards with 455.7mm clearance and seven expansion slots.
- Offers two height options for motherboard installation, allowing flexible fan and CPU cooler setups.
- Improved cable management with Velcro straps, dual-layered clips, and a 15mm protruding PSU bracket for extra space.
Cons
- Installing a 420mm AIO can block EPS 12V cable routing and may prevent 3x 140mm bottom fans from fitting due to motherboard cable collision.
- Rear fan support is limited, unable to fit two 120mm fans.
- The included I/O ports are considered limited by some users.
- Not optimized for air-cooled builds, despite some design changes.
- 12VHPWR cables for modern GPUs can be tight against the side glass panel, requiring careful routing or pre-bending.
Dimension Scores
The case supports extensive liquid cooling with up to a 420mm top radiator and 360mm side/bottom radiators, facilitating high thermal output.
While the case itself doesn't generate noise, its open design and lack of included fans mean noise levels are entirely dependent on user-chosen components, with 140mm fans generally being quieter at similar airflow.
Constructed with tempered glass and steel, the case features a robust, modular design with a removable pillar and reversible chassis, indicating high build quality.
Cable management is a highlight, with Velcro straps, dual-layered clips, and a 15mm PSU bracket protrusion providing ample space and organization options.
Best For
- Enthusiasts building custom liquid-cooled systems with multiple large radiators.
- Showcase builds where an unobstructed view of internal components and RGB lighting is a priority.
- Users with large E-ATX motherboards and extended graphics cards (up to 455.7mm).
- Builders who appreciate modularity and the ability to reverse the chassis orientation.
Not Recommended For
- Budget-conscious builders looking for a simple, cost-effective case.
- Users primarily focused on air cooling, as the case's design is heavily geared towards liquid cooling.
- Compact desk setups, due to its larger size compared to the original O11D EVO.
Watch Out For
- A 420mm AIO radiator can block EPS 12V cable routing, making installation difficult.
- Using 3x 140mm fans at the bottom is often impossible due to collision with motherboard headers and cables, especially in 'Lower Mode'.
- The 12VHPWR cable for high-end GPUs can be a tight fit, potentially pressing against the tempered glass side panel without careful management or a 90-degree adapter.
- Top passthroughs to the back chamber might be too small for some AIO pump tubes if not top-mounting the radiator.
- The case does not include any fans, requiring additional purchase for any cooling setup.

What Buyers Say
Users frequently praise the O11D EVO RGB for its stunning aesthetics, particularly the L-shaped ARGB strips and the seamless view offered by the removable front pillar. The increased internal space and support for large radiators and GPUs are also highly valued, making it a favorite for high-end liquid-cooled builds. However, some builders encountered difficulties with 420mm AIO installations, noting conflicts with EPS 12V cables and bottom fan placement. The case's limited rear fan support and potentially tight 12VHPWR cable clearance are also recurring points of concern.
“This case looks amazing with the glass and RGB, but seriously, trying to get that 420mm AIO in with the EPS cables was a nightmare, and my bottom fans barely fit. Still, it's gorgeous once it's all done.”
Common Praise
- Removable front support bar creates a clean, unobstructed view of components.
- L-shaped ARGB lighting on the top and bottom panels looks visually appealing.
- Ample room for large graphics cards, including RTX 4080 models.
- Improved cable management features, including Velcro straps and dual-layer clips.
- Supports multiple 140mm fans on top, side, and bottom for enhanced airflow.
- Modular design with reversible chassis and adjustable motherboard height offers build flexibility.
Common Complaints
- Installation of 420mm AIOs can be problematic, interfering with EPS 12V cables.
- Bottom 140mm fan placement can conflict with motherboard headers and cables.
- Limited I/O ports compared to some other cases.
- The 12VHPWR cable for GPUs can be very tight against the side glass panel.
- Cannot fit two 120mm fans in the rear.
- Some users desire a removable motherboard tray or more advanced cable management from other Lian Li models.
Ownership Tips
- The L-shaped RGB strips are easy to control and sync with motherboard software, adding significant aesthetic value.
- The dual-chamber design really helps keep cable clutter out of sight, making for a much cleaner build.
- Even with the increased size, fitting a 420mm AIO requires careful planning, especially regarding cable routing near the top of the motherboard.
- The removable front pillar is a game-changer for showcasing components, but remember to handle the glass panels carefully during removal.
- The ability to adjust motherboard height offers unexpected flexibility for optimizing fan placement and airflow, which is a subtle but powerful feature.
Frequently Asked Questions
Does this case come with fans?
No, the Lian Li O11D EVO RGB does not include any fans, so you will need to purchase them separately to complete your cooling setup.
Can I install a 420mm radiator in this case?
Yes, the case supports a 420mm radiator on the top, but be aware that installing it can make routing EPS 12V cables challenging.
Is the front support pillar removable?
Yes, the front support pillar can be removed to provide a seamless, unobstructed view of your internal components.
How is the cable management in this case?
The case is designed with cable management in mind, featuring Velcro straps, dual-layered clips, and an additional 15mm of space behind the PSU mounting bracket.
Can I fit a large graphics card like an RTX 4080?
Yes, the case has 455.7mm of GPU clearance, accommodating large cards like the ASUS ROG STRIX RTX 4080, though the 12VHPWR cable might be a tight fit against the glass.
Can the motherboard be installed at different heights?
Yes, the internal layout allows for two height options for motherboard installation, offering flexibility for fan and CPU cooler placement.
Buying Guide
When buying a PC case like this, you need to think about more than just looks. Consider the size of your components, especially your graphics card and any liquid cooling radiators you plan to use. Airflow is crucial for keeping your system cool, so look at fan and radiator support. Cable management features will save you a lot of headaches during the build process and keep your interior looking clean.
E-ATX compatibility
This means the case can fit larger motherboards than standard ATX, giving you more options for high-end components and features. Think of it like a bigger garage for a bigger, more powerful car.
420mm radiator support
This indicates the case can accommodate very large liquid cooling radiators, which are essential for efficiently cooling powerful, high-performance CPUs and GPUs, especially if you're overclocking. It's like having a super-efficient cooling system for your engine.
Dual-chamber design
This separates the main components (motherboard, GPU) from the power supply and drives, improving airflow to heat-sensitive parts and making cable management much easier. It's like having a separate utility room to hide all the messy pipes and wires.
455.7mm GPU clearance
This is the maximum length of a graphics card that will fit. Modern high-end GPUs are very long, so this spec tells you if your monster graphics card will have enough room without hitting the front of the case.
Alternatives
If this case is too large or liquid cooling isn't your priority, look for mid-tower cases with better dedicated airflow for air coolers, or smaller form factor cases if desk space is limited.
