Extended Product Information
FAQs
What motherboard sizes does this case support?
The Lian Li O11 Dynamic Mini V2 Flow supports ATX, Micro-ATX (M-ATX), and Mini-ITX motherboards. It also offers exclusive compatibility for ATX Back-Connect motherboards.
Does the case come with fans?
Yes, the case comes with five high-quality, pre-installed reverse-blade PWM fans. These fans provide strong and silent cooling right out of the box, optimized for airflow.
Can I install my graphics card vertically?
Yes, the package includes both horizontal and vertical GPU brackets, along with an adjustable anti-sag support. This allows you to choose your preferred GPU orientation and ensures stability.
How does the dual-chamber design improve my PC build?
The dual-chamber design separates the main heat-generating components (motherboard, GPU, CPU) from the power supply, storage drives, and cables. This separation optimizes airflow for critical components, improves thermal performance, and allows for significantly cleaner cable management on the back side.
How do I move or remove the front I/O module?
The I/O module is designed for flexible placement at either the top or bottom of the front panel. You can detach it from its current position and re-attach it to the desired alternative location. The bottom I/O module can also be removed entirely to enhance bottom intake airflow.
What is an ATX Back-Connect motherboard, and why is it important for this case?
An ATX Back-Connect motherboard routes all its power and data connectors to the rear of the motherboard tray, rather than the front. This case offers exclusive compatibility for such motherboards, enabling an exceptionally clean interior aesthetic with virtually no visible cables in the main chamber, ideal for showcase builds.
How do I keep my case clean and maintain good airflow?
Regularly clean the removable dust filters, especially on intake areas. Use compressed air to clear dust from internal components like fans and heatsinks. Ensure fans are correctly oriented for intake and exhaust, and keep internal cables tidy to prevent obstruction of airflow paths.
Troubleshooting
Poor airflow or overheating components
Ensure all pre-installed fans are connected and spinning. Check for dust buildup on filters and fans, especially intake areas. Verify correct fan orientation (intake/exhaust) for optimal thermal performance. Ensure no cables are obstructing airflow paths within the case.
Front I/O ports (USB, audio) are not working
Confirm that all front panel connectors are correctly and securely plugged into the corresponding headers on your motherboard. Refer to your motherboard manual for the correct pinouts for USB, audio, and power/reset switches.
Difficulty with cable management
Make full use of the dual-chamber design. Utilize the provided 24-pin cable bracket and 9 dedicated cable straps to organize and secure cables in the rear chamber. Plan your cable runs before installing all components to simplify the process.
Graphics card (GPU) sag despite using the bracket
Ensure the adjustable anti-sag support is properly positioned directly beneath the heaviest part of your graphics card and tightened securely. Double-check that the GPU is fully seated in its PCIe slot.
Case fans are louder than expected
The case includes PWM fans; ensure they are connected to PWM headers on your motherboard (usually 4-pin headers). Adjust fan curves in your motherboard's BIOS/UEFI settings or through fan control software to optimize speed for desired noise levels, reducing RPMs during idle or light loads.
Pros and Cons
Pros
Excellent airflow performance due to thoughtful design and pre-installed fans
Stunning aesthetics with tempered glass and superior cable management options
High versatility in component and cooling configurations (motherboards, GPUs, radiators)
Includes useful accessories like GPU brackets and anti-sag support
Quiet operation from high-quality reverse-blade PWM fans
Exclusive compatibility with ATX Back-Connect motherboards for ultra-clean builds
Cons
While called 'Mini', it is still a mid-tower case and not suitable for ultra-compact builds
Full potential of ATX Back-Connect support requires specific motherboard hardware
> Info needed: Potential limitations on specific radiator/fan configurations at certain points.
Tempered glass panels add weight, making the case less portable
> Info needed: Compatibility with extremely long GPUs or tall CPU air coolers might be tight.
Setup, Compatibility & Care
Setup Instructions
Preparation: Unpack the case and remove the tempered glass panels by detaching their securing points. Identify the accessory box containing screws, cable ties, and brackets.
Motherboard Installation: Install the appropriate standoffs for your ATX, M-ATX, or Mini-ITX motherboard. Place the motherboard into position and secure it with screws. If using an ATX Back-Connect motherboard, ensure all connections are routed through the rear access points.
Power Supply Unit (PSU): Install your PSU in the rear chamber. Route the main power cables (e.g., 24-pin ATX, 8-pin EPS) through the rubber grommets to the main chamber.
Cooling (Fans/Radiators): Mount additional fans or radiators as desired. The adjustable motherboard standoffs allow for flexibility in radiator placement. Utilize the tool-less fan covers for specific fan mounting locations to direct airflow.
Graphics Card (GPU): Choose between horizontal or vertical mounting using the included brackets. Install your GPU into the PCIe slot and use the adjustable anti-sag support to secure it firmly.
Storage Drives: Install 2.5" SSDs or 3.5" HDDs into the dual-purpose drive cages located in the rear chamber.
Cable Management: Utilize the built-in 24-pin cable bracket and the 9 dedicated cable straps to route and secure all cables neatly in the rear chamber. This is crucial for maintaining optimal airflow and a clean aesthetic in the main chamber.
I/O Module Placement: Decide whether to place the front I/O module at the top or bottom of the case. Connect the I/O cables (USB, audio, power switch) to your motherboard headers.
Compatibility Guidelines
Motherboards: ATX, Micro-ATX (M-ATX), Mini-ITX. Exclusive support for ATX Back-Connect motherboards.
Power Supply: Supports ATX PSUs. > Info needed: Max PSU length.

Storage: Dual-purpose drive cages support multiple 2.5" SSDs and 3.5" HDDs.
Care & Maintenance
Dust Filters: Regularly remove and clean the magnetic dust filters (located on intake fan areas) with water and mild soap, or simply vacuum them. Ensure they are completely dry before re-installing.
Tempered Glass Panels: Clean the tempered glass panels using a soft, microfiber cloth and a non-abrasive glass cleaner. Avoid harsh chemicals that could damage the glass or surrounding finishes.
Interior Cleaning: Periodically use compressed air to blow out dust from internal components, especially fan blades, heatsinks, and hard-to-reach areas. Ensure your system is powered off and unplugged before cleaning.
Fan Maintenance: Check fan blades for any dust buildup and gently clean them with a soft brush or compressed air. Ensure no cables are obstructing fan operation.
