Montech AIR 903 MAX ARGB E-ATX Gaming Casing White

The Montech AIR 903 MAX ARGB E-ATX Gaming Case is a premium airflow-focused mid-tower built for enthusiasts who demand high cooling, component compatibility, and visual flair, all in one well-engineered chassis. It supports large motherboard form factors including E-ATX and SSI-EEB, along with ATX, Micro-ATX, and Mini-ITX, so you have flexibility for high-end builds. The front panel is a metal mesh with about 51% ventilation rate, which combined with four preinstalled HP140 fans (three 140 mm ARGB fans up front + one 140 mm non-ARGB exhaust at the rear) ensures excellent airflow right out of the box. For cooling options, it accommodates large CPU air coolers up to 180 mm tall, graphics cards up to 400 mm long, ATX power supplies up to 240 mm deep, and supports radiator mounting up top and front (up to 360 mm) plus multiple fan positions for up to nine fans total, giving you solid liquid cooling or high-airflow builds. Storage is well covered: there are mounts for 2 × 3.5-inch HDDs and up to 5 × 2.5-inch SSDs scattered in convenient and hidden locations for clean builds. The case also includes a USB Type-C port + 2 USB 3.0, audio and mic jacks, LED control and reset buttons on the front I/O, and a tempered glass side panel for showing off the internals. Cable management is decent with ~27 mm routing space, rubber grommets and Velcro straps. Dimensions are about 478 × 230 × 493 mm, weighing roughly 7.8-8 kg depending on color, so it’s large but not overbearingly so for a full-feature airflow case.
