Caja de PC Lian Li O11D Mini-X Mini Tower negra

The Lian Li O11D Mini-X is a compact Mini Tower PC case in black that balances a small footprint with extensive water-cooling capability. It supports Mini-ITX, Micro-ATX and ATX motherboards, accepts SFX power supplies, and accommodates multiple fan and radiator placements including front 120 mm, side 120/140 mm and top 120/140 mm mounts. The case offers flexible expansion with modular back panels and space for both 2.5" and 3.5" drives while measuring 269.5 mm (W) × 420 mm (D) × 380 mm (H).

Advantages

The modular back panel provides three interchangeable I/O slot configurations (3/5/7) so you can match expansion to your build. A side-radiator bracket with a 30 mm clearance behind the fan allows fresh-air intake and room for long GPUs in a compact chassis. Multiple pump-stand positions (flat, elevated, floating) support different pump and radiator layouts. Dual-chamber cable routing with rubber grommets, tie points and an SSD mounting bar helps keep cables tidy. Magnetic dust filters on all intake sides plus a removable dust tray protect internal components.

Suitable for

• Compact water-cooled gaming or workstation builds
• Systems requiring long GPUs in a small chassis
• Custom radiator and pump configurations (single or multiple radiators)
• Builders who need flexible expansion slot layouts or vertical GPU mounting

How to use

Choose the appropriate modular back panel (3, 5 or 7 slots) for your expansion cards before installing the motherboard. Install the SFX power supply and position drives in the dedicated 2.5" or 3.5" bays. For water-cooling, decide on radiator placement (front, side or top) and select a pump-stand position — flat at the bottom, elevated beside a 240/280 mm radiator, or floating above a 120 mm fan — then secure the pump and route tubing. Use the rubber-grommeted openings to pass cables into the second chamber, secure them with the provided tie points or Velcro channels, and mount SSDs on the SSD bar to maintain clearance for the right-side panel.

Recommendations

To maintain airflow and component longevity, install the magnetic dust filters on all intake sides and clean them regularly. When planning a side-radiator with a long GPU, use the 30 mm clearance behind the side fan bracket to ensure adequate intake and allow proper GPU clearance. Consider the vertical GPU kit if you need an alternate GPU orientation; adjust the back panel position to avoid interference with bottom fans or radiators.
