Left-side tempered glass panel for Lian Li A3-mATX chassis — black

Replacement left-side tempered glass panel designed specifically for the Lian Li A3-mATX chassis in a black finish. This OEM-fit panel provides a transparent viewing window that integrates with the original case design, offering both visual access to internal components and a rigid protective barrier against dust and minor impacts. It is dimensioned and drilled to align with the A3-mATX mounting points, ensuring straightforward installation and consistent fit.

Advantages

The tempered glass construction delivers superior scratch resistance and structural rigidity compared with standard acrylic panels, while the black finish offers a clean, uniform look that complements dark-themed builds. As a direct replacement part, it preserves original airflow pathways and mounting positions and avoids the need for modifications. The panel reduces visible dust accumulation on components and helps protect delicate hardware from accidental contact.

• Owners of the Lian Li A3-mATX chassis requiring a direct replacement for a damaged or missing left-side panel
• PC builders seeking a black tempered-glass aesthetic for showcasing internal components
• Technicians performing maintenance or repairs who need an OEM-fit panel to restore the chassis
• Users upgrading from acrylic or opaque panels to tempered glass for improved durability and clarity

Key specifications

How to use

Remove the original left-side panel by loosening the external fasteners or thumbscrews and lifting the panel away from the chassis. Align the replacement tempered glass panel with the case mounting points and carefully lower it into position, ensuring screw holes and rubber grommets (if present) are aligned. Secure the panel using the original fasteners or equivalent hardware, applying even pressure and avoiding over-tightening to prevent stress on the glass. Check that the panel sits flush and that edges are fully seated before returning the chassis to service.

Recommendations

Handle the tempered glass panel on a flat, soft surface and use gloves or a lint-free cloth to avoid fingerprints. When fastening, tighten screws gradually and evenly. Clean with a soft microfiber cloth and mild glass cleaner; avoid abrasive pads or ammonia-based cleaners. Inspect mounting points periodically for loose fasteners to maintain a secure fit.
