The Lian Li O11 Dynamic EVO (O11DEG) in Harbor Grey is a dual-chamber mid-tower case built from 4 mm aluminium, 4 mm tempered glass and a 1 mm steel structure. Its signature feature is a reversible layout: the motherboard tray and front I/O can be flipped between normal and reverse modes so the glass side always faces your desk. It takes E-ATX boards up to 280 mm wide, graphics cards up to 426 mm, CPU air coolers up to 167 mm and as many as three 360 mm radiators or ten fans. Storage is generous with up to nine drives, and the front panel adds USB 3.1 Type-C alongside two USB 3.0 ports. A showcase chassis for custom builds in Saudi Arabia.
