The be quiet! Light Base 900 FX White is a full-tower showcase PC case with fully windowed front and side tempered-glass panels, built for enthusiasts who want their high-end E-ATX build on full display. Identified by part number BGW72, it pairs a spacious dual-chamber interior with four pre-installed Light Wings 140mm PWM ARGB fans and a large wrap-around ARGB LED strip, so the whole system becomes the centerpiece of the room. Support for motherboards up to E-ATX and XL-ATX (including back-connector designs), graphics cards up to 495 mm and two 420 mm radiators makes it suited to extreme air- or water-cooled builds. Typically in stock with fast delivery across Cyprus.

Frequently Asked Questions
Does the Light Base 900 FX fit E-ATX and back-connector motherboards?
Yes. It supports motherboards up to E-ATX and XL-ATX, including modern back-connector (rear-cable) boards, with a long motherboard tray and a dual-chamber layout that keeps cables hidden.
Is the Light Base 900 FX suitable for a custom water-cooling loop?
It is built for it. Detachable brackets in the top and bottom each hold a radiator up to 420 mm, and the side accepts up to 360 mm, allowing up to three radiators simultaneously alongside an E-ATX board.
What is the difference between the Light Base 900 FX and the 900 DX?
Both share the same chassis, glass panels and cooling support. The FX (BGW72) ships with four pre-installed Light Wings 140mm ARGB fans, while the DX comes without fans for builders who prefer to fit their own.
What do I need to know before buying the Light Base 900 FX White?
It is a large full-tower (532 x 327 x 484 mm, ~15.8 kg) and does not include a power supply - you will need a standard ATX PSU. Plan for the space and a PSU separately; the four ARGB fans and GPU holder are already included.
Singular Expert Insight
If your goal is a no-compromise showcase build, the 900 FX is the top model of the Light Base line: you get the four ARGB fans, the largest radiator support and XL-ATX clearance out of the box. Builders who already own their preferred fans can save by choosing the otherwise identical Light Base 900 DX, while anyone with a tighter desk should look at the smaller Light Base 600 series (ATX, up to 360mm radiators). For the same case in a darker theme, the Black variant (BGW71) is identical apart from colour.
Buyer’s Guide
Buy it if
You want a panoramic showcase for a high-end E-ATX/XL-ATX build, plan heavy water-cooling (up to 2x 420mm) and run a long GPU up to 495 mm.
Skip it if
You need a compact case for a small desk - at ~84 L and 15.8 kg this full tower is large, and it needs a separate ATX PSU.
Also consider
The Light Base 900 DX (same case, bring your own fans), the Black 900 FX (BGW71), or the smaller Light Base 600 for ATX builds.
