be quiet! BGW71 Light Base 900 FX Full Tower E-ATX Case

The be quiet! BGW71 Light Base 900 FX is a full-tower E-ATX case built for builders who want their system on display. Large windowed front and side panels, a 3-metre ARGB LED strip with 172 LEDs, and a relocatable-foot design that flips to inverted or horizontal layout in seconds make it a centrepiece as much as a chassis. It suits enthusiasts running multi-radiator liquid cooling loops or large E-ATX motherboards who refuse to compromise on visual impact.Why This Product Panoramic glass front and side panels — Tempered glass panels on both the front and side give an unobstructed view of every component inside, making it ideal as a showcase build. 172-LED ARGB strip visible from all angles — A 3-metre strip wrapping the interior can be controlled via the included ARGB button or synchronised through the motherboard for custom colours and effects. 4 pre-installed Light Wings 140mm PWM fans — One rear exhaust and three side-intake fans with reversed blades ship installed, so the system looks as good as it performs straight out of the box. Switch layout in seconds — Relocatable feet let you convert to an inverted or horizontal layout without tools or lengthy disassembly — just lift, reposition and continue. Dual 420mm radiator support simultaneously — Detachable radiator and fan brackets in the top and bottom each accommodate a 420mm radiator, with a third mounting point in the side supporting up to 360mm. Supports backside-connector motherboard designs — The two-chamber layout routes cables and drives behind the motherboard tray, and the case explicitly supports modern boards with rear-connector designs.

Best For / Trade-offsBest for: Showcase or open-side display builds — windowed front and side panels plus a 172-LED ARGB strip make every component visible from multiple angles. High-end liquid cooling configurations — simultaneous support for two 420mm radiators and a third 360mm radiator covers even the most ambitious custom-loop layouts. Large E-ATX and XL-ATX platform builds — the extra-spacious interior is designed around the biggest consumer motherboard form factors. Builders who reconfigure their desk layout frequently — the relocatable-foot system allows inverted or horizontal orientation changes in seconds without disassembly. Clean cable-management builds — the two-chamber design keeps drives and cables tucked behind the motherboard tray, away from the windowed chambers. Trade-offs: Small-form-factor or compact builds — at 484 × 327 × 532 mm and 16,800 g this is a large, heavy enclosure that requires substantial desk or floor space. PSUs longer than 225 mm — units exceeding the stated maximum length will not fit. Builders needing multiple 3.5" drive bays — only one internal 3.5" bay is provided; additional spinning-disk storage will require adapters or external solutions. Builds with more than 8 expansion cards — the case provides exactly 8 expansion slots, limiting multi-GPU or heavy add-in card configurations beyond that count. Low-profile or acoustically critical environments — the large windowed panels and open airflow design prioritise visibility and thermal headroom over noise isolation.
