For years, we PC builders have been caught in a frustrating compromise. On one hand, the allure of a small, desk-friendly computer is undeniable. A compact build looks cleaner, takes up less physical and visual space, and feels more modern. On the other hand, the reality of high-performance components—towering air coolers, lengthy graphics cards, and the need for robust power supplies—often pushes us towards cavernous, full-sized towers. I remember a build from a few years back where I tried to cram a powerful rig into a “compact” case that barely fit the GPU, leaving cable management a nightmare and thermals a constant worry. The result was a system that was technically small but functionally choked. This is the dilemma many of us face: do we sacrifice performance for size, or desk space for power? It’s a choice that shouldn’t have to be made, and it’s precisely this problem that the Lian Li O11 Dynamic Mini V2 PC Case White sets out to solve once and for all.
- FULL-SIZE POWER, MINI FOOTPRINT: Despite its compact design, this small form factor case offers ample space for powerful full-size hardware and high-performance AiO water cooling.
- FLEXIBLE GPU INSTALLATION: Mount your graphics card horizontally or vertically – brackets for both options included.
What to Consider Before Buying a Compact ATX PC Case
A PC case is more than just a box to house your components; it’s the foundation of your entire build, dictating everything from thermal performance and noise levels to the ease of assembly and future upgradeability. A well-chosen case can make building a pleasure and ensure your expensive hardware runs cool and quiet for years. Conversely, a poor choice can lead to overheating, frustrating cable management, and limitations on the parts you can use. The primary benefit of a compact ATX case like this one is its ability to offer the best of both worlds: support for powerful, standard-sized components within a significantly reduced footprint. It’s about achieving a high-performance build without the monolithic tower dominating your space.
The ideal customer for this type of product is an enthusiast who values both aesthetics and performance. This is for the builder who wants to create a showpiece rig with powerful hardware, perhaps including custom water cooling, but prefers a more refined and space-conscious setup. It’s perfect for those living in apartments or who simply desire a clean, minimalist desk. However, it might not be the best fit for absolute beginners on a strict budget, as the premium features come at a cost. It’s also not ideal for users who need a vast number of 3.5-inch hard drive bays for a home server or mass storage setup. For those users, a larger, more traditional mid-tower or full-tower case would be a more practical choice.
Before investing, consider these crucial points in detail:
- Dimensions & Component Clearance: This is paramount in any build, but especially in a compact case. You must verify clearance for your CPU cooler height, your graphics card length and width, and your power supply unit (PSU) size. The Lian Li O11 Dynamic Mini V2 PC Case White is exceptional in that it supports full ATX motherboards and PSUs, but you still need to be mindful of fitting the absolute largest flagship GPUs, which may require careful maneuvering.
- Cooling Capacity & Airflow: A smaller internal volume can trap heat more easily, making airflow design critical. Look for features like mesh panels, ample fan mounts, and radiator support. This case supports up to nine fans and multiple radiators, including a 360mm one, which is outstanding for its size and crucial for taming the heat from high-end CPUs and GPUs.
- Materials & Build Quality: The materials dictate the case’s look, feel, and longevity. Cheaper cases often use thin, flexible steel and acrylic side panels that scratch easily. A premium case will use thick-gauge alloy steel, aluminium, and high-quality tempered glass, resulting in a sturdy, rattle-free build that feels substantial and looks fantastic.
- Ease of Use & Modularity: A great case should make the building process enjoyable, not a chore. Features like a dual-chamber layout for hiding cables, removable panels and brackets, and tool-less drive sleds are signs of a well-thought-out design. The modularity of the O11 Mini V2, with its configurable back panel and movable I/O, is a defining feature that provides unparalleled flexibility.

First Impressions: Premium, Polished, and Packed with Possibilities
From the moment you lift the box, you can tell the Lian Li O11 Dynamic Mini V2 PC Case White is a serious piece of kit. At over 10 kilograms, it has a reassuring heft that speaks to its quality construction. Unboxing it, we were greeted by perfectly formed foam packaging protecting the pristine white finish and flawless tempered glass panels. The first thing that struck us was the quality of the finish; the powder coating is smooth, consistent, and brilliantly white, providing a perfect canvas for any build. There are no thin, flimsy panels here—the alloy steel feels rigid and robust.
What truly sets the initial experience apart is the generous accessory kit. Lian Li includes a well-organized plastic case containing every screw you could possibly need, neatly sorted and labelled. They also provide plenty of zip ties, a GPU anti-sag bracket, and, most impressively, all the brackets required for a vertical GPU mount (minus the riser cable). This is a huge value-add, as these kits are often expensive optional extras from other brands. Pulling off the side panels—which pop off smoothly with a firm tug—reveals the intelligently designed interior. The dual-chamber layout is immediately apparent, promising a clean build by hiding the PSU and drive cages out of sight. It feels less like a restrictive box and more like a modular platform, ready and waiting for your vision. You can see its full list of included accessories and modular features on its product page.

A Deep Dive into the Lian Li O11 Dynamic Mini V2 PC Case White’s Performance
A case can look great on the outside, but its true worth is revealed during the building process and in its long-term performance. We put the Lian Li O11 Dynamic Mini V2 PC Case White through its paces with a high-end ATX build to see if its beauty was more than skin deep. We focused on the entire user experience, from the ease of assembly and cable management to its thermal capabilities and component compatibility.
The Building Experience: A Masterclass in Modularity and Cable Management
Building in the Lian Li O11 Dynamic Mini V2 PC Case White is, simply put, a joy. This is where the dual-chamber design truly shines. By moving the power supply, storage drives, and the bulk of your cabling into a separate compartment behind the motherboard tray, the main chamber is left beautifully open and uncluttered. This not only creates a stunning showcase for your core components but also makes the entire assembly process remarkably straightforward. As one user aptly noted, even if you’re not skilled in cable management, this case makes it easy to achieve a clean result without force. We found this to be absolutely true; there are ample tie-down points, well-placed rubber grommets, and generous space in the rear chamber to tuck away excess cables without having to wrestle the back panel shut.
The modularity is another standout feature. The entire case can be disassembled with relative ease, giving you unobstructed access from almost any angle. The rear panel is reconfigurable, allowing you to shift the motherboard up or down to prioritise radiator clearance at the top or bottom. We tested this with a 360mm All-in-One (AiO) liquid cooler mounted to the top, and by adjusting the motherboard position, we had plenty of clearance from our RAM modules and motherboard heatsinks, a common pain point in smaller cases. The front I/O panel can also be relocated from the top to the bottom front of the case, a thoughtful touch that allows you to optimize its position based on whether your PC will sit on your desk or the floor. Everything from the tool-less panel removal to the well-machined screw holes makes the process feel polished and premium. This level of builder-focused design is a significant advantage over more restrictive cases.
Cooling Without Compromise: Airflow and Thermal Performance
One of our biggest initial questions was whether a case this compact could effectively cool a high-TDP processor and a power-hungry graphics card. The answer is a resounding yes. The design is engineered for maximum airflow. With mesh panels at the top and side, along with a ventilated bottom, there are numerous pathways for air to enter and exit. The case supports a staggering nine 120mm fans: three on the top, three on the bottom, two on the side, and one on the rear. This flexibility allows for a multitude of cooling configurations to suit any build.
For our test, we configured three bottom fans as intake, a 360mm AiO on the top as exhaust, and two side fans as intake. This setup created a positive pressure environment that bathed the GPU and motherboard in cool air. We were incredibly impressed with the results. Under a combined CPU and GPU stress test, temperatures remained well within excellent ranges, rivaling those we’ve seen in much larger cases. This confirms the sentiments of users who praise its “superbe airflow” and low temperatures even with fans running at quiet speeds. A particularly clever feature, also highlighted by a reviewer, is the angled bottom fan bracket. This small design choice helps direct the intake air more effectively towards the GPU fans, ensuring the component that needs it most gets a direct supply of fresh air. Whether you’re planning an elaborate custom water-cooling loop or a high-airflow air-cooled setup, the Lian Li O11 Dynamic Mini V2 PC Case White provides the thermal headroom you need.
Big Power, Small Footprint: Unprecedented Component Compatibility
The single most impressive feat of the Lian Li O11 Dynamic Mini V2 PC Case White is its ability to house full-size, standard components without the usual “compact case” compromises. The V2 revision makes a critical improvement over its predecessor by officially supporting standard ATX power supplies. This is a game-changer, as it opens up a much wider and more affordable range of PSU options compared to the SFX/SFX-L units required by the original. We installed a standard 160mm ATX PSU with ease, leaving plenty of room for cable routing.
The case also comfortably fits full ATX motherboards, giving you access to more features, PCIe slots, and connectivity than smaller ITX or Micro-ATX boards. This combination of ATX motherboard and ATX PSU support in a chassis of this volume is remarkable. Furthermore, the GPU support is extensive. It includes brackets for both traditional horizontal mounting and a stunning vertical mount. We found the included anti-sag bracket to be effective and easy to install for the horizontal configuration. However, it’s important to heed the advice from some users: while the case supports long GPUs, the latest generation of flagship cards (like the RTX 4080/4090 series) are not just long but also incredibly wide and tall. As one user noted, fitting one of these behemoths requires patience and careful maneuvering. We recommend double-checking the exact dimensions of your chosen graphics card against the case’s specifications to ensure a smooth installation.
What Other Builders Are Saying
Across the board, user feedback for the Lian Li O11 Dynamic Mini V2 PC Case White is overwhelmingly positive. A common thread is the praise for its premium build quality, with one user stating it’s “high quality, as always with Lian Li,” and another noting it’s made of “high-quality” materials, not “thin sheet metal like you’re used to from cheap cases.” The excellent airflow and builder-friendly design are also frequently celebrated. One builder called it “one of the best cases I’ve ever built in,” citing the solid materials, great airflow, and how cable management is “a breeze.”
The value proposition is another key highlight, with one German user calling it the “Best case for around €90” and praising the inclusion of the vertical GPU mount and ample accessories as “very strong.” However, the feedback isn’t without its minor criticisms, which align with our own findings. The most consistent point of caution, mentioned in a French review, is the tight fit for very large, modern graphics cards. The user advised that “on big GPUs you will have to have patience” to install them without forcing anything. This is crucial advice for anyone planning to use a top-of-the-line GPU and underscores the importance of pre-planning your build.
How the Lian Li O11 Dynamic Mini V2 PC Case White Compares to the Competition
While the O11 Dynamic Mini V2 is a phenomenal case, the market is filled with excellent options. Here’s how it stacks up against three strong alternatives, each catering to a slightly different builder.
1. Corsair 3500X ARGB Mid-Tower PC Case

- High Cooling Capacity: Side, roof, and PSU fan mounting points, accommodating up to 10x 120mm fans, ensure that you don’t sacrifice cooling for the stunning looks of a glass front panel.
The Corsair 3500X is a direct competitor in the “showcase” category, featuring a similar panoramic tempered glass design that wraps around the front and side. Its main advantage is that it comes with three pre-installed ARGB fans, offering great value for builders who want RGB lighting out of the box. It also has excellent support for new “reverse connection” motherboards for an even cleaner look. However, the Lian Li O11 Dynamic Mini V2 PC Case White offers superior modularity with its configurable rear panel and has a more refined, less overtly “gamer” aesthetic. The Corsair is a great choice for those who want an all-in-one RGB showcase, while the Lian Li is the better platform for pure customisation.
2. Fractal Design North Charcoal Black ATX Mid Tower PC Case
- Enhance the look of your gaming station with sleek wood and alloy details
