Overview
The Lian Li O11 Dynamic EVO RGB (Model: O11DERGBX) is an E-ATX mid tower chassis finished in black, constructed from a combination of 4.0mm tempered glass, aluminium, and steel. It builds on the proven O11D EVO platform with a slightly enlarged footprint — 478mm (D) × 290mm (W) × 471mm (H) — that translates directly into broader component compatibility across every axis. The defining visual feature is a pair of 1.5mm thick L-shaped ARGB strips positioned at the very top and bottom of the chassis. These strips support 14 selectable lighting effects with independent brightness and colour controls accessible via front-panel buttons, and they can synchronise with compatible motherboard RGB headers. The front pillar is fully removable, delivering an unobstructed view of installed hardware through the tinted front and side tempered glass panels without compromising the case structure. Cooling headroom is a standout attribute. The top position accommodates radiators up to 420mm (a separate bracket is required for 420mm installations), while both the side and bottom positions accept radiators up to 360mm. Alternatively, each of the three main positions — top, side, and bottom — supports up to three 120mm or three 140mm fans, with a single 120mm fan position at the rear, for a maximum of ten fans in total. Quick-release fan brackets on all three sides can be removed without tools, and the side bracket is reversible, offering four distinct installation orientations. Motherboard compatibility spans E-ATX (under 280mm width), ATX, Micro-ATX, and Mini-ITX form factors. Two sets of pilot holes at different heights let builders shift the motherboard tray position to suit their preferred layout or to clear specific cooling configurations. GPU clearance reaches 455.7mm maximum, and CPU cooler height is supported up to 167mm. Storage capacity is generous: the side fan bracket accepts 2× 3.5-inch HDDs or 4× 2.5-inch SSDs, the hard drive cage holds a further 2× 3.5-inch HDDs or equivalent 2.5-inch SSDs, and two additional 2.5-inch SSD mounts sit behind the motherboard tray — totalling up to 4× 3.5-inch HDDs and 8× 2.5-inch SSDs. Seven expansion slots accommodate multi-GPU or add-in-card configurations, with optional accessories available separately for vertical or upright GPU mounting. Cable management is addressed through large hook-and-loop velcro straps near the PSU chamber, dual-layer cable clips sized for both thick and thin cables, and an additional 15mm of depth behind the PSU chamber wall. A single bottom dust filter protects the intake zone.
