The chassis packs support for M-ATX and ITX boards, a 415mm GPU, and up to a 360mm radiator into a 26.3L volume, making it a rare combination of small footprint and real performance potential. The build is minimalistic and mesh-heavy, so anyone after tidy thermals and a clean, compact system should consider it.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimalistic steel mesh panels:\u003c\/strong\u003e Side and top steel mesh help maintain airflow while keeping the exterior visually restrained.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVersatile motherboard support:\u003c\/strong\u003e Accepts both M-ATX and ITX boards with four expansion slots for flexible component choices.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLong GPU compatibility:\u003c\/strong\u003e Can accommodate up to a 415mm graphics card, so large GPUs fit without compromise.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMultiple PSU formats:\u003c\/strong\u003e Supports ATX, SFX, SFX-L and LIAN LI Edge PSU installations sideways or frontways for layout flexibility.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh cooling capacity:\u003c\/strong\u003e Designed to take a 360mm radiator and up to ten 120mm fans, enabling strong liquid and air cooling setups.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact 26.3L volume:\u003c\/strong\u003e Delivers a small desktop footprint while retaining significant component support for performance builds.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThe A3-mATX suits enthusiasts who need a compact, performance-capable enclosure for gaming or workstation builds where thermal performance matters as much as saved desk space.
