PC-behuizing Lian Li PC-A3X Micro Tower zwart

The LIAN LI & DAN Cases A3-mATX is a compact Micro Tower PC case that balances a minimal chassis footprint with support for large, high-performance components. It features mesh panels on three sides, a sleek front panel and a relocatable PSU bracket so you can build a powerful yet compact M-ATX system tailored to your needs.

Advantages

The case offers strong ventilation through three mesh-sided panels and supports multiple fan and radiator layouts. Toolless removal of exterior panels and modular internal brackets simplifies installation and cable routing. A removable bottom dust filter helps keep components clean, while flexible internal space accommodates large GPUs and tall CPU coolers when layout choices are optimized.

Suitable for

• Compact gaming or workstation builds using Micro-ATX or Mini-ITX motherboards
• High-performance single-GPU systems with large components
• Users who prioritise airflow and easy maintenance
• Systems requiring multiple storage options (2.5" and 3.5" drives)

Key specifications

• Form factor: Micro Tower (supports Micro-ITX and Micro-ATX)
• Maximum GPU length: 415 mm (note: with a 25 mm bottom fan installed GPU thickness limited to 61 mm / 3-slot)
• Maximum CPU cooler height: 165 mm
• Drive bays: supports 2.5" and 3.5" drives (2 x 2.5" bays indicated in product data)
• Front/top/rear fan support: 120 mm and 140 mm side fans; 120 mm rear and top fans
• External ports: 2 × USB 3.2 Gen 1 Type-A

How to use

Install a Micro-ATX or Mini-ITX motherboard and position the PSU on the relocatable bracket according to your chosen internal layout. Fit the CPU cooler up to 165 mm tall and select a GPU length up to 415 mm while checking available thickness if additional bottom fans or radiators are used. Remove exterior panels without tools for component installation and routing cables through the case before replacing panels and connecting external peripherals via the front USB ports.

Recommendations

For best airflow and component clearance, plan your cooling configuration before installation: avoid installing a bottom 25 mm fan together with a 4-slot thick GPU, and verify radiator+fan placements as they may preclude GPU installation. Regularly clean the removable bottom dust filter to maintain cooling performance.
