LIAN LI O11 Dynamic EVO Dual-Chamber Mid-Tower Case – Harbor Grey | O11DEG
The LIAN LI O11 Dynamic EVO Harbor Grey (O11DEG) is a premium dual-chamber mid-tower PC case featuring front and side tempered-glass panels, a reversible chassis, integrated ARGB front lighting, and extensive cooling flexibility. It supports E-ATX motherboards, GPUs up to 426mm, up to 10 fans, and three 360mm radiators, making it ideal for high-end gaming and custom liquid-cooled builds.
Product Overview
The LIAN LI O11 Dynamic EVO combines the showcase styling of the O11 series with a highly flexible dual-chamber layout. The front and side tempered-glass panels provide a clear view of the system, while the secondary chamber keeps the PSU, storage, and cable management separated from the main hardware area.
The official color of this version is Harbor Grey, rather than Silver. LIAN LI combines a grey-coated mesh panel and Harbor Grey aluminum exterior with dark tinted tempered glass, a black interior, light-grey rubber grommets, and black feet.
One of the O11 Dynamic EVO's standout features is its reversible chassis. The system can be assembled in the traditional Normal Mode or flipped into Reverse Mode, allowing the panoramic glass viewing area to face the opposite side. The bottom-mounted I/O module can also be repositioned to suit different orientations.
Cooling support is extensive, with room for 3 × 120mm fans at the top, side, and bottom, plus a 120mm rear fan, providing support for up to 10 main cooling fans. The case can accommodate 360mm radiators at the top, side, and bottom simultaneously, making it particularly suitable for elaborate custom water-cooling systems.
The chassis supports E-ATX motherboards under 280mm wide, as well as ATX, Micro-ATX, and Mini-ITX boards. It provides up to 426mm GPU clearance, 167mm CPU cooler clearance, and support for ATX power supplies up to 220mm. The dual-chamber layout can even accommodate two power supplies when configured appropriately.
Storage capacity is equally impressive, with mounting provisions for up to nine 2.5-inch SSDs, or various combinations of SSDs and HDDs. Optional accessories are available for vertical GPU mounting, upright GPU installation, additional I/O, a front mesh conversion, and top-mounted I/O.
Please check the official manufacturer website for the latest and most accurate compatibility, clearance, radiator, fan, and I/O specifications before purchase or finalizing a build.
