- Width230Height475Depth498mm(9.1 × 18.7 × 19.6 in)2Maker product pagemaingear.com/pages/mg-1Read 15 October 2026The page lists 475 mm (W) x 498 mm (D) x 230 mm (H), 18.70 x 19.60 x 9.05 in. The W and H labels look swapped. The case is an upright tower with a narrow side, and the maker's older MG-1 and Zero entries list the narrow side as width. Tom's Hardware gives 18.78 x 19.65 x 9.06 in without labels. The setup guide labels 18.78 W, 19.65 H and 9.06 D. Stored as width 230, height 475 and depth 498, as the case sits on a desk. Maker rounding differs by 2 mm from the review.

Windows Central confirms the trio of 140mm front fans. Tom's Hardware's open table counts 4x 120 mm case fans in total. The setup guide lists 120 mm intake fans. These conflict. The maker's 140 mm is stored. A possible rear exhaust fan is not stored, because no open source states its position and size.
