Its defining feature is the patented three-panel tempered-glass arrangement across the front, top, and left side. This creates a broad, largely uninterrupted view of the motherboard, graphics card, memory, and cooling hardware. Compatibility with back-connect motherboards can further clean the visible area by moving cable terminations behind the tray, and the top mesh panel accepts a 360mm AIO radiator.

The second chamber has a particularly thoughtful purpose: when an AIO is mounted on the side, its tubing can be concealed within that chamber. This is more than a cosmetic trick because it preserves the visual appeal of a side-mounted cooler without simply leaving tubes and radiator edges in view. The mesh top also allows intake or exhaust airflow without sacrificing the clean geometric appearance of the glass panel.

The main trade-off is that the case is optimized around visual refinement and compact proportions rather than maximum internal volume. No pre-installed fans are listed, so cooling hardware and appropriate airflow will need to be added. For a builder pairing a back-connect motherboard with a side-mounted AIO, however, this focus is highly compelling, making the O11 Vision Compact ATX the strongest all-around visual choice here.

Choose it when a panoramic view, hidden tubing, and back-connect support matter more than having a large collection of fans already installed. It suits compact gaming systems, showcase builds, and creators who want a restrained but premium-looking enclosure.

Panoramic Glass and Minimalist Presentation

The front, top, and left tempered-glass panels create one of the most expansive viewing areas in the guide. The design keeps structural elements from interrupting the principal sightline, allowing coordinated components, lighting, and cooling hardware to become the visual focus.

Purposeful Back-Connect and AIO Design

Back-connect motherboard support reduces visible cable clutter, while the second chamber hides the tubing of a side-mounted AIO. Together, these details allow the case to look clean without asking the builder to compromise on cooling hardware.

We may earn a commission when you buy through this link, at no additional cost to you.

Four PWM-controlled 120mm ARGB fans arrive with daisy-chain connectivity, making the initial cooling setup more convenient. An integrated 26-LED ARGB strip adds another lighting element and can be synchronized through motherboard software. The enclosure also supports ATX, Micro-ATX, Mini-ITX, and both back-connect ATX and back-connect Micro-ATX motherboards.

Internal room is generous for a mid-tower. The supplied specifications list graphics cards up to 420mm, CPU coolers up to 178mm, and a top radiator up to 360mm. Tool-less mechanisms on both side panels simplify access, which is valuable during initial assembly and later upgrades involving memory, storage, or the power supply.

Its limitations are mostly relative. Compared with dual-chamber showcase models, it does not provide the same separated cable compartment or expansive glass presentation, and the supplied fan set includes only one rear exhaust fan. Still, those trade-offs are reasonable for a value-focused build that arrives with substantial cooling hardware already installed.

This is a strong recommendation for builders who want ATX flexibility, ARGB lighting, and immediate fan performance without turning every accessory into a separate purchase. It is particularly practical for gaming systems that need room for a long graphics card and a capable top-mounted cooler.

Cooling and Lighting Out of the Box

Four daisy-chained 120mm ARGB fans reduce the need for additional purchases, and their PWM control allows motherboard-managed speed adjustment. The integrated light strip extends the visual effect beyond the fans, creating a more finished appearance immediately after installation.

Useful Mid-Tower Flexibility

Support for 420mm graphics cards, 178mm CPU coolers, and a 360mm top radiator covers most mainstream enthusiast hardware. The tool-less side-panel mechanisms make routine access faster without detracting from the enclosure's structure.

A 10-degree slanted bottom section directs intake air through the lower chamber, which the supplied information says can improve GPU cooling. Five 120mm reverse-blade fans are positioned at deliberate angles for this airflow path. Reverse blades also keep the front-facing surfaces visually consistent, producing a subtler look than a cage of illuminated fans.

The layout remains capable for demanding components. It accepts standard ATX, Micro-ATX, and Mini-ITX motherboards and is optimized for ATX back-connect boards. Both horizontal and vertical GPU anti-sag brackets are included, offering flexibility for different card orientations and reducing strain on a heavy graphics card.

The tradeoff is that this is not a lighting showcase model, since the included fans are explicitly non-RGB. Detailed radiator sizing is also not included in the supplied specifications, so builders planning an AIO should verify fit directly. Even so, the combination of five fans, angled intake, and anti-sag support is unusually complete for a compact enclosure.

Choose the O11D Mini V2 Flow for a clean, airflow-oriented system with a large graphics card. It is a particularly logical option when reverse-blade fans and physical GPU support matter more than synchronized RGB effects.

Angled Intake for GPU Cooling

The slanted bottom design channels incoming air through the lower region of the chassis, where the graphics card commonly generates the most heat. Combined with the angled reverse fans, it forms a deliberate cooling strategy rather than relying only on installed fan quantity.

Flexible Heavy-GPU Support

Horizontal and vertical anti-sag brackets accommodate different mounting preferences and help support a heavy card. This flexibility is useful when a builder wants to optimize desk space, airflow, or the final visual orientation.

We may earn a commission when you buy through this link, at no additional cost to you.

Cooling begins with two pre-installed 170mm ARGB front fans and one 140mm ARGB rear fan. The large front pair moves substantial air through the intake area, while the rear fan provides exhaust. The infinity-mirror treatment allows the front lighting to extend the visual depth of the chassis, making the included fans part of the overall effect rather than simple functional additions.

A relocatable I/O module can sit at the top or bottom, allowing the builder to place the power, reset, and other controls closer to a preferred cable route. M1 and M2 buttons provide direct control of the front-panel lighting and ARGB fan lighting. Synchronization through motherboard software or a wireless controller is also supported.

The power supply can be mounted in two orientations and supports units up to 220mm long. This flexibility helps builders balance cable routing, airflow, and available space. The trade-off is that 170mm front fans are less universally compatible with radiators and other large front-mounted cooling solutions than standard 120mm or 140mm fans.

Choose this case when the front of the system should immediately catch attention and a coordinated ARGB appearance is central to the build. It pairs that visual identity with a practical adjustable I/O, flexible power-supply placement, and a strong set of pre-installed fans.

A Front Panel with Depth

The tempered-glass infinity-mirror treatment creates a layered visual effect that differs from a conventional ARGB strip. Large front fans sit behind the panel, adding visible motion and reinforcing the sense of depth when the lighting is active.

Control Placement and Power Flexibility

Moving the I/O module between the upper and lower portions of the case makes it easier to align with a preferred cable path. Dual power-supply orientations and support for units up to 220mm add useful adaptability behind the dramatic exterior.

Two 160mm ARGB front fans and one 140mm rear fan are pre-installed. Fine mesh covers the front, top, and side of the power-supply shroud, providing ventilation across several paths. The removable top radiator bracket simplifies liquid-cooling installation, while a seal plate helps prevent pressure loss when using a smaller radiator or a 120mm fan arrangement.

The case supports E-ATX motherboards up to 280mm wide, ATX, Micro-ATX, and Mini-ITX formats. Graphics cards can reach 392mm, and CPU cooler clearance is listed at 180mm in air-cooled mode. Storage provisions cover two 3.5-inch hard drives and six 2.5-inch solid-state drives on dedicated mounts.

Cable management is aided by a full-length grommet bar, Velcro straps, and smaller clips. The modular motherboard I/O can move to a higher or lower position to suit air-cooled or water-cooled configurations. The principal drawback is that this is a deep chassis, so buyers should confirm it fits the available space and consider the visual impact of a large mid-tower.

Choose the LANCOOL 216 RGB for a roomy, conventional dual-chamber design that handles long cards, multiple drives, and large cooling hardware well. It is a strong fit for established gaming builds where ventilation and organized cabling matter alongside a clean tempered-glass presentation.

Mesh-Enhanced Airflow in Several Directions

Front, top, and shroud-side mesh panels create multiple paths for air movement. The included 160mm front fans move substantial volume, while the rear 140mm fan helps complete a basic intake-and-exhaust arrangement.

Built for Large and Numerous Components

Buying Guide – How to Choose the Best Lian Li PC Cases

The right Lian Li PC case depends on motherboard size, graphics-card length, cooling plan, available space, and preferred display style. Compatibility checks should come before aesthetic preferences because a visually appealing enclosure cannot accommodate the hardware it was not designed for.

Motherboard Form Factor and Back-Connect Support

Begin with the exact motherboard standard and connector layout. Standard ATX, Micro-ATX, and Mini-ITX boards are supported by many of the larger cases, while the O11 Vision-M mATX and Vector V100 MINI do not accept full-size ATX. Several models also explicitly support back-connect variants, which can reduce visible cable clutter but requires a compatible board and matching connectors.

Graphics Card Length and Orientation

Modern graphics cards can be longer than many people expect, so use the case's stated clearance rather than estimating from a photograph. The included limits range from 392mm in the LANCOOL 216 RGB to 455.7mm in the O11 Dynamic EVO RGB. Builders using thick triple- or quad-fan cards should also allow for power-cable clearance and any vertical-mounting bracket.

CPU Cooler Height

Air coolers need more vertical space than a low-profile AIO, and the listed limits range from 162mm in the O11 Vision-M mATX to 178mm in the V100-ATX. The LANCOOL 216 RGB also lists 180mm in air-cooled mode. A compact case with a moderate-height tower cooler can have less side-panel clearance than its exterior dimensions suggest.

Radiator Size and Fan Placement

Radiator support depends on both the mounting position and the case's width. Top support ranges from 240mm or 360mm in several models to 420mm in the O11 Dynamic EVO RGB, which also supports 360mm radiators on the side and bottom. Large 170mm and 160mm front fans can be excellent airflow options, but they may restrict radiator choices in that position.

Pre-Installed Fans and Airflow Direction

Pre-installed fans reduce assembly work and provide a baseline cooling layout. Counts range from one 140mm fan in the O11 Vision-M mATX to seven 120mm RGB fans in the O11 Dynamic EVO RGB. The O11D Mini V2 Flow uses five reverse-blade fans and a slanted bottom intake, while the Vector V100 MINI concentrates four intake fans along the side. Reverse-blade fans also change the visual orientation of the fan face.

Power Supply Length and Orientation

Power-supply clearance includes the unit's body, modular cables, and the space required to bend and route them. The LANCOOL 217 INF provides two mounting orientations and accepts units up to 220mm, while the O11 Dynamic EVO RGB also supports power supplies up to 220mm. Smaller cases list tighter limits, including ATX units under 182mm in the O11 Vision-M mATX.

Second-Chamber Cable Management

A separate chamber can keep power leads, storage wiring, and liquid-cooling lines away from the visible component area. The O11 Vision Compact, LANCOOL 216 RGB, O11 Dynamic EVO RGB, and O11 Dynamic EVO XL RGB all use dual-chamber concepts. The LANCOOL III adds magnetic covers, while the O11D Mini V2 Flow includes a 24-pin bracket for a tidier motherboard connection.

Case Size, Storage, and Daily Access

Exterior size affects desk placement, component clearance, and the total hardware configuration possible. The Vector V100 MINI is compact in intent but measures 436 by 221.5 by 443.9mm, while the LANCOOL III reaches 526 by 238 by 523mm. Storage capacity varies too, with the LANCOOL III supporting up to twelve 2.5-inch SSDs and the LANCOOL 216 RGB offering six dedicated 2.5-inch mounts.

How to Use and Care for Your Lian Li PC Cases

Before installing components, compare the motherboard, graphics card, power supply, CPU cooler, and cooling hardware against the case specifications. Remove panels only after laying the case on a protected surface, and keep the tempered glass away from hard, dirty, or sharply edged surfaces. Follow the included hardware guide for the correct screw locations and bracket orientation.

Install the power supply and storage devices first, then route their cables through the cable-management openings before fitting the graphics card. Connect fans and RGB devices using the specified headers, and route tubing or cables so they do not interfere with fans. Connect storage data cables to the correct motherboard or controller ports, and confirm that the graphics card has adequate power and physical support.

After the build is complete, check that every fan spins in the intended direction, all panels are firmly seated, and no cable blocks a fan or radiator. Use filtered dust management and keep intake paths unobstructed. For tempered-glass panels, clean with a soft microfiber cloth and a suitable cleaner, avoiding harsh chemicals and moisture around the edges. Review the product documentation before removing covers, and allow adequate airflow around the completed system.
