Description
The InWin A3 redefines the expectations for compact PC builds by merging a sleek, minimalist aesthetic with the versatility required for high-performance hardware. Despite its small 29.9L volume, this Micro-ATX chassis accommodates triple-slot graphics cards and standard ATX power supplies, making it an ideal choice for users who refuse to compromise on power for size. The vertical airflow layout and pre-installed Mercury AM120S silent fan ensure optimal thermal management in a sophisticated SECC steel and tempered glass enclosure.
This product is for:
- Minimalist Enthusiasts: Users seeking a clean, professional look with tinted tempered glass and a tool-less design.
- SFF Builders: Those transitioning from mid-towers who want a smaller footprint without sacrificing Micro-ATX motherboard features.
- High-Performance Gamers: Builders needing space for 340mm GPUs and 162mm CPU air coolers.
- Content Creators: Professionals requiring fast data transfers via the front-panel 20Gbps USB-C port.
- Quiet PC Advocates: Users who prioritize low noise levels, facilitated by the included slim-profile AM120S PWM fan.

Building in the InWin A3 is a streamlined experience thanks to its tool-less side panels and intuitive internal layout. The vertical airflow design leverages natural convection, pulling cool air from the bottom to exhaust heat through the top and rear. The inclusion of the Mercury AM120S fan provides excellent static pressure and airflow while maintaining a slim 20mm profile, allowing for more clearance during installation. Cable management is simplified by the strategic placement of the PSU shroud, which supports standard ATX units, though builders should note the interplay between PSU length and GPU clearance to ensure a perfect fit.
Compared to traditional mid-tower cases, the InWin A3 offers a significantly smaller desk footprint while maintaining compatibility with mainstream Micro-ATX boards, which often provide better VRM cooling and more PCIe slots than Mini-ITX alternatives. While smaller than the InWin A5, the A3 retains the same premium build quality and high-speed I/O. It stands out against competitors in the sub-30L category by offering a dedicated 20Gbps Type-C port and the flexibility to house larger air coolers that typically require much bulkier cases.
Q&A:
- What is the maximum GPU length supported by the InWin A3? The case supports graphics cards up to 340mm, though using a power supply longer than 170mm will limit GPU clearance to 280mm.
- Can I install a liquid cooler in this case? Yes, the top panel supports a 240mm radiator for efficient CPU cooling.
- Does the case come with any fans? The InWin A3 includes one pre-installed Mercury AM120S slim silent fan at the rear.
- What type of USB ports are on the front panel? It features one ultra-fast USB 3.2 Gen 2x2 Type-C port (20Gbps) and two USB 3.2 Gen 1 Type-A ports.
- Is the side panel made of plastic or glass? The A3 features a premium tinted tempered glass side panel for a clear view of your internal components.
