PC Case Lian Li O11Dynamic XL Midi Tower White

The Lian Li O11Dynamic XL Midi Tower in white is a versatile PC case with a bottom-mounted power supply layout and a spacious interior that supports large components and multiple storage drives. It accepts motherboards up to E-ATX, accommodates both 2.5" and 3.5" drives, and offers extensive cooling options including top, side and rear fan mounts and space for radiators. The exterior combines tempered glass, SGCC and aluminium elements and includes front I/O with four USB 3.2 Gen 1 Type-A ports.

Advantages

The case features hot-swappable drive bays for replacing or adding storage without shutting down the system, an aluminum exterior with a tidy I/O layout, and tool-free access with a push-and-hold top panel release. It provides upgraded cooling support with room for additional 120 mm fans and thick radiators, flexible GPU mounting with eight expansion slots supporting dual or vertical GPU layouts, and removable magnetic dust filters for easy maintenance.

Suitable for

• Custom gaming and enthusiast builds requiring large GPUs or dual GPU configurations
• Water-cooled systems using distro-plate and DDC pump solutions
• Users who need frequent drive replacement or expansion (hot-swap)
• Builds demanding strong airflow and multiple radiator mounting options

How to use

Install the power supply in the bottom compartment, mount the chosen motherboard (ITX to E-ATX) and route cables using the dedicated management channels. Fit storage drives into the interchangeable drive trays or hot-swap bays as required. For water cooling, use the EKWB-designed 01 ID distro-plate with its multiple inlet and outlet ports and install the DDC3.1 pump where recommended. Secure GPUs either horizontally or use the vertical/dual GPU configuration supported by the eight expansion slots. Use the front panel RGB controls to sync addressable RGB with a compatible motherboard or switch lighting modes directly from the panel.

Recommendations

For optimal airflow and cleaner internals, install magnetic dust filters on intake locations, leave space for thicker bottom radiators when planning dual-GPU or vertical GPU layouts, and use the hot-swap bays for backup or archival drives to avoid system downtime during storage changes.
