Our take on the Be Quiet! Light Base 900 DX White

The Light Base 900 DX is Be Quiet!'s full-tower showcase case, built around a glass-and-steel frame with addressable RGB lighting and a dual-chamber layout. It swallows E-ATX and XL-ATX boards, 495 mm graphics cards and 190 mm CPU coolers, and it holds up to ten 120 mm or 140 mm fans plus multiple radiators. The DX version adds a mesh top and side intake option for airflow builds, which sets it apart from the solid-panel Light Base 900. It suits builders who want a large, lit display case for a high-end system rather than a compact or silent-focused enclosure.
