Minimalistic Approach to PC Aesthetics

The tinted tempered glass side panel complements the A3’s overall modern vibe. The front panel is pristinely clean and is embellished with a golden sheet.

Install High-end GPUs

The A3 is a space-efficient chassis. It’s smaller than most Micro-ATX cases. Despite this, it can house high-end graphics cards of different sizes, including up to 3-slot GPUs.

Build Small. Play Big.

This case is compatible with SFF-Ready Enthusiast GeForce cards, so you can pack high performance into a smaller footprint. Look for SFF-Ready Enthusiast GeForce Cards to get a sure fit and streamline your PC build.

Stuff It With Hardware!

This mini tower can support up to Micro-ATX system builds, while accommodating high-end graphics cards and power supply.

* PSUs longer than 170 mm will need to build with GPUs 280 mm or shorter.

The A3 supports multiple 2.5” / 3.5” storage devices. The case offers strategically placed channels behind the motherboard tray for clean and easy cable management.

Vertical Airflow Layout

Since heat rises, the A3’s internal layout works in accordance to this fact. The top and bottom feature ventilated filter panels to combat dust and heat. With the PSU secured at the front, air can naturally propel upwards in the main chamber.

Don’t Screw Yourself! Go Screwless!

The toolless tinted tempered glass side panel offers a refreshing view of the internal hardware! Meanwhile, the top panel, steel side panel, and bottom filter are screwless too for easy access and cleaning.

Know I/O?

The A3 features one USB 3.2 Gen 2x2 Type-C port, two USB 3.2 Gen 1 Type-A ports for fast charging speeds and outstanding data transfer rates and a headset audio jack utilizing the international CTIA standard.
