The O11 Dynamic EVO XL is Lian Li’s large full-tower case with glass panels. It takes E-ATX boards, graphics cards up to 460 mm, three 420 mm radiators at once and 11 fans, and offers a reverse layout, relocatable front I/O and optional upright/vertical GPU brackets. Testing found it well suited to custom water cooling, with cable routing and the missing RGB hub criticised. Owners praise build quality and ease of assembly; the size and lack of included fans come up often.

Lian Li presents the O11 Dynamic EVO XL as the largest and most flexible case in the EVO series, with support for three 420 mm radiators and a modular design. Lian Li
On KitGuru’s white sample, looping Cinebench R23 and 3DMark Speed Way for 60 minutes (19–21 °C ambient) gave an average CPU delta of 72 °C and 42 °C for the upright-mounted GPU; mounting the GPU horizontally cut its temperature by a couple of degrees, and adding side fans cooled the CPU by a couple of degrees. The detachable front I/O can be moved to the front, side or rear. The large interior, support for three 420 mm radiators, multiple GPU mounting options and reverse layout were praised; the lack of an RGB hub, the PSU getting in the way of rear cable routing and basic builds looking lost inside were criticised. The review recommends the standard EVO for AIO-only builds.
KitGuru: Lian Li O11 Dynamic EVO XL reviewOn LDLC the black EVO XL averages 10 out of 10 from 28 reviews. guillaumekoliak (May 2026) praises the reverse mode, the large cable space behind the tray and build quality, but notes the case is big and heavy when full and comes without fans. QuevinP (November 2025) fitted an RTX 5090 but received the inner glass panel slightly scratched, KarlJ (March 2025) likes the airflow but finds the bottom front USB awkward with the case on the floor, and JerryD (September 2024) praises easy assembly and ventilation options. A missing-screw review for the white version was not counted for this model.
