Lian Li O11D EVO XL vs be quiet! Dark Base Pro 901

The O11D EVO XL is the better pick for custom-loop builders and anyone who wants a showcase build with maximum radiator and fan capacity. The Dark Base Pro 901 is the better pick for quiet, storage-heavy or workstation builds, and it ships with three Silent Wings 4 140mm fans and a touch-sensitive I/O panel. The Lian Li wins on airflow layout and build flexibility; the be quiet! wins on out-of-box cooling, noise and drive capacity. Owners of both praise build quality, but the Dark Base is heavier and larger, and the O11D needs fans bought separately.

• Choose the Lian Li O11D EVO XL if you plan a custom water loop or a glass-and-RGB showcase build and want reversible layout and up to three 420mm radiators.
• Choose the be quiet! Dark Base Pro 901 if you want a quiet, storage-rich full tower that arrives with three quality fans and tool-free, touch-controlled access.
