Computer Case InWin A3 Mini-Tower Tempered Glass - Black

The InWin A3 Mini-Tower Tempered Glass in black is a compact computer case designed for modern PC builds. It features a tempered glass side panel that provides clear visibility of internal components while maintaining a compact footprint that fits on or under most desks. The case supports ATX, Micro-ATX and Mini-ITX motherboards and is engineered to accommodate common cooling layouts and cable routing for a tidy interior and efficient airflow.

Advantages

The tempered glass panel offers durable, scratch-resistant visibility of internal components without sacrificing structural integrity. Support for multiple motherboard sizes and a standard internal layout allows flexible component selection, including standard-length graphics cards and multiple storage drives. The black finish gives a neutral aesthetic that integrates with diverse setups while the interior space is arranged to simplify cable management and cooling installations.

Suitable for

• Compact gaming or productivity builds using ATX, Micro-ATX or Mini-ITX motherboards
• Systems where component visibility is desired (RGB lighting or showcase builds)
• Workspace or home setups that require a small-footprint, modern-looking case

Key specifications

• Form factor: Mini-tower compatible with ATX, Micro-ATX and Mini-ITX motherboards
• Side panel material: Tempered glass
• Finish color: Black
• Cooling support: Multiple fan and radiator mounting options for standard cooling configurations
• Drive bays and storage: Dedicated mounts for 2.5" and 3.5" drives (varies by internal configuration)
• Expansion: Standard PCI expansion slots suitable for typical full-length graphics cards

How to use

Install the chosen motherboard into the standoffs provided and secure it with screws. Mount the power supply in the designated area and connect power cables to the motherboard, drives and peripherals. Fit storage drives into the drive mounts and attach any graphics card or expansion cards into the PCI slots. Route cables through available cutouts and secure them with cable ties or straps to maintain airflow. Install fans or liquid-cooling radiators according to the case’s supported mounting locations, and reattach the tempered glass panel once assembly and cable routing are complete.

Usage recommendations

For optimal thermal performance, plan fan placement to create a clear airflow path (intake at the front/bottom, exhaust at the rear/top) and avoid blocking vents with cables. Use modular or semi-modular power supplies when possible to reduce cable clutter. Regularly clean dust filters and the tempered glass surface with appropriate cleaning products to maintain visibility and cooling efficiency.
