M3 - Round

Built on the legacy of the M1 Classic and M2, the M3 (previously called M2-AC168) continues NCASE’s commitment to precision-engineered SFF (small form factor) design — now with more flexibility and headroom. M3 supports Micro-ATX motherboards, 168mm air coolers like the Noctua NH-D15 G2, and oversized GPUs such as the ROG ASTRAL 5090 and MSI SUPRIM 5090, all within a compact footprint. Crafted from CNC-machined aluminum and available in the classic Grater Silver and Round Black, the M3 is designed for builders who want more — without leaving SFF behind.
