Overview

The Lian Li O11 AIR MINI is a compact mini tower case that delivers exceptional airflow and expandability in a small footprint. Finished in white, this case features high-density mesh panels on the front, top, and side, paired with two pre-installed 140mm PWM fans and one 120mm PWM fan for excellent cooling out of the box. The combination of brushed aluminum and tempered glass gives it a premium, modern aesthetic that suits both gaming rigs and professional workstations. Despite its compact dimensions (384mm wide, 400mm deep, 288mm high), the O11 AIR MINI supports ATX, Micro-ATX, and Mini-ITX motherboards via a modular back panel. It can accommodate power supplies up to 200mm long, graphics cards up to 362mm, and CPU coolers up to 170mm tall. This makes it a versatile choice for builders who want high-end components without a full-tower footprint. Positioned as a mid-to-high-end airflow-focused case, the O11 AIR MINI is ideal for users who prioritize cooling performance and build quality in a space-saving design.

Product Info

Released in late 2021, the Lian Li O11 AIR MINI typically retails between $100 and $130 USD (pricing varies by region and retailer). It comes with three pre-installed PWM fans (2x140mm, 1x120mm) and carries a standard 2-year manufacturer warranty. This case targets the mid-to-high-end segment, offering a balance of compact size, strong airflow, and premium build materials.

Best Use Cases

High-Performance Gaming in a Compact Build: The O11 AIR MINI fits ATX motherboards and long GPUs, making it perfect for gamers who want a powerful system without a full tower. The mesh panels ensure components stay cool under load. Airflow-Focused Workstations: For content creators running demanding CPUs and GPUs, the excellent ventilation and support for large coolers and radiators provide reliable thermal performance. Aesthetic Builds: The white aluminum and glass design looks clean and modern, especially when paired with RGB lighting. It's a great choice for builders who value visual appeal.

Things to Consider

No E-ATX Support: If you need an E-ATX motherboard, consider the larger O11 Dynamic series instead. Radiator Clearance: Installing a 280mm radiator in the front may limit GPU length. Also, a top 240mm radiator might interfere with tall CPU coolers. Plan your component layout carefully. Stock Fans Are Adequate but Not Silent: The included fans provide good airflow but are not the quietest on the market. Enthusiasts may want to replace them with quieter alternatives. * Price Premium: The O11 AIR MINI is slightly more expensive than some competitors in its class, but the build quality and expandability justify the cost for most users.
