It supports Micro‑ATX or Mini‑ITX motherboards, GPUs up to 344 mm, and 166 mm air coolers. Two 120 mm ARGB front fans sit behind a DarkMirror panel with side mesh intakes, with mounts for six 120 mm fans plus front/top/rear radiators. The case includes an ATX PSU bay, a tempered‑glass side panel, and basic front I/O with dual USB 3.2 Gen 1 and audio jacks. A movable drive cage lets you trade space between the PSU and a front radiator.Sourcecoolermaster.com
