Caja de PC Lian Li A3-mATX Micro Tower blanca con detalles en madera — compatible con Micro-ATX/Mini-ITX, fuentes ATX/SFX/SFX-L

The Lian Li A3-mATX Micro Tower in white with wood-coloured accents is a compact PC case designed for Micro-ATX and Mini-ITX builds. With external dimensions of 194 × 443 × 321.5 mm (26.3 L), the chassis balances a minimalist look and extensive component support: accommodates up to a 4-slot GPU with a maximum length of 415 mm, CPU coolers up to 165 mm in height, and supports ATX, SFX and SFX-L power supplies. The case features mesh panels on three sides for improved airflow, modular, toolless exterior panels and brackets for easier installation and cable management, and removable dust filters to keep the interior clean.

Advantages

The A3-mATX provides a small form factor without sacrificing compatibility: it supports large GPUs and multiple PSU form factors, and includes an anti-sag GPU bracket for stable graphics card installation. Mesh panels on the sides and top and a wood-accent front panel combine ventilation with a refined aesthetic. Modular, toolless components and a removable SSD tray let you relocate drives or the PSU bracket to optimize layout and cooling. Multiple PSU mounting positions and an ATX offset bracket help accommodate longer graphics cards and various cooling configurations.

Suitable for

• Compact gaming or content-creation PCs where space is limited
• Micro-ATX or Mini-ITX builds requiring full-size GPU support
• Systems that need flexible PSU placement (ATX, SFX, SFX‑L)
• Users who prefer tool-less access and modular interior layouts

How to use

Install the chosen Micro-ATX or Mini-ITX motherboard on the provided standoffs, then position the PSU in the preferred mounting slot (ATX, SFX or SFX-L) using the included brackets. Mount storage drives to the removable SSD tray or bottom drive point as required. Fit the GPU while noting the available thickness and clearance when bottom fans or radiators are installed; use the supplied anti-sag bracket to secure longer or heavier cards. Attach cooling fans or radiator assemblies to the front, top, or rear mounting points according to your thermal requirements, and slide the mesh panels back on for optimal airflow. The toolless exterior panels allow quick access for cable routing and component adjustments.

Recommendations

For best thermal performance, use mesh side/top panels with at least one intake and one exhaust fan and consider mounting a 360 mm AIO if using high-power components. When installing a thick bottom fan or radiator, verify GPU thickness clearance; use the ATX offset bracket or alternative PSU positions to maximize space for longer graphics cards. Keep the bottom dust filter clean to maintain airflow and cooling efficiency.
