Case PC Lian Li O11 Dynamic EVO XL Tower nero

The Lian Li O11 Dynamic EVO XL Tower in black is an enlarged mid/large tower case designed to accommodate modern high-performance PC components while offering flexible modularity. It supports E-ATX motherboards (up to 280mm wide), multiple storage drives, and extensive cooling options including up to three 420mm radiators. Constructed with aluminum panels with fine mesh, tempered glass and steel elements, the chassis balances a refined appearance with effective airflow and dust protection.

Advantages

The O11D EVO XL provides a removable front pillar for an unobstructed hardware display, an ARGB front light strip with motherboard sync, and an open bottom with multiple dust filters for improved ventilation. Tool-less and quick-release features simplify installation: adjustable fan brackets, a removable anti-sag GPU bracket (GB-003) for heavy graphics cards, and a movable motherboard tray with three height positions for versatile fan/radiator layouts. The case also includes a relocatable modular I/O with USB-C and USB-A ports and multiple mounting points for pumps and storage.

Suitable for

• High-performance gaming PCs with large GPUs
• Custom liquid-cooling builds requiring multiple radiators (up to 3 × 420mm)
• Workstations needing E-ATX motherboards and extensive storage
• Systems where easy airflow management and dust filtration are priorities

How to use

Install the chosen motherboard (up to E-ATX) on the adjustable tray and set the tray height according to your fan and radiator configuration. Mount storage drives in the accessible drive locations or the bottom drive cage; remove the cage if you need access to the hidden D5/DDC pump mounting point. Use the tool-less fan brackets and quick-release mechanisms to fit fans or radiators, and secure the GPU with the included anti-sag bracket (adjust height as required). Connect the ARGB strip to a compatible motherboard header for synchronized lighting through the modular I/O ports.

Recommendations

For best thermal performance, plan radiator placement across the top, side and bottom positions and keep magnetic and nylon filters clean. When building with heavy GPUs or multiple radiators, use the anti-sag bracket and verify clearance for radiators at each tray height setting.
