AI Verdict
This is a 15.3 kg E-ATX dual-chamber case with panoramic glass, ARGB lighting, and flexible layout options for builders prioritizing aesthetics and extensive liquid cooling capacity.
This case is a strong fit for enthusiasts building high-end systems focused on aesthetics and advanced cooling. Its support for E-ATX motherboards, multiple 420mm radiators, and a 495mm GPU clearance means it can house nearly any component. The panoramic glass and extensive ARGB lighting are clearly for display-oriented builds.
If you need individual ARGB control for each fan, look for cases that include a more advanced ARGB controller or plan to purchase a third-party one.

Pros
- Supports up to two 420mm radiators and one 360mm radiator simultaneously, allowing for extensive liquid cooling setups.
- Features a 3-meter ARGB LED strip with 172 LEDs and motherboard synchronization for customizable lighting.
- Offers inverted and horizontal layout configurations, quickly changeable by removing feet.
- Includes two ARGB and PWM hubs with a total of 12 ports for connecting fans and lighting.
- Accommodates E-ATX motherboards and graphics cards up to 495mm in length.
- Comes with a flexible graphics card holder that supports both horizontal and vertical GPU installations.
Cons
- Does not include any pre-installed fans, requiring separate fan purchases.
- The integrated ARGB hub sends a single signal, preventing individual control of connected fans/ARGB lights via the hub.
- 140mm fans can produce a buzzing resonance noise when mounted due to proximity to the 120mm fan lattice, potentially requiring spacers.
- The front panel may have a loose fit on one side.
- Accessing the bottom dust filter can be challenging when the case is in an upright position.
Dimension Scores
The case supports up to two 420mm radiators and one 360mm radiator, providing exceptional cooling potential for high-performance components.
While be quiet! is known for quiet products, this case includes no fans, and 140mm fan installations can create a buzzing resonance noise.
Constructed from alloy steel, tempered glass, and plastic, with reviewers noting strong and sturdy construction, though a loose front panel has been reported.
The dual-chamber design and support for back-connect motherboards allow for cables and drives to be neatly tucked away behind the motherboard tray.
Best For
- Showcase PC builds with extensive ARGB lighting and visible components.
- Custom liquid cooling loops requiring multiple 420mm and 360mm radiator support.
- E-ATX system builders needing ample space for large motherboards and GPUs.
- Users who want the flexibility to switch between upright and horizontal case orientations.
Not Recommended For
- Budget-conscious builders who need included fans.
- Users who prioritize individual ARGB control for each fan via a single hub.
- Anyone sensitive to potential fan resonance with 140mm fan installations.
Watch Out For
- No fans are included, so factor in the cost of up to 10 fans for cooling.
- The integrated ARGB/PWM hubs don't allow for individual fan or ARGB control; all connected devices will sync to the same pattern.
- Installing 140mm fans can lead to a 'buzzing' resonance noise due to the case's internal lattice, which might require purchasing 10-15mm fan spacers.
- The front panel might not be perfectly secure, with reports of one side being loose.
- Removing the bottom dust filter for cleaning is difficult if the case is kept upright.

What Buyers Say
This case is a big, open canvas for showing off your PC, especially if you're into liquid cooling and ARGB. People really dig the panoramic glass and how easy it is to flip the whole thing around or lay it flat. But, you're buying a shell; no fans come with it, so budget for those. Also, if you're planning on 140mm fans, be ready for a potential buzzing sound that might need some DIY fixes.
“Man, this case looks sick with all the glass and lights, but seriously, no fans? And my 140s buzz like crazy, gotta figure out some spacers or something. Still, my E-ATX board fits, and my giant GPU looks awesome in there.”
Common Praise
- The fully windowed front and side panels offer a clear view of internal components.
- The 3-meter ARGB LED strip provides extensive and customizable lighting.
- The ability to quickly switch between inverted and horizontal layouts is a standout feature.
- The case provides ample space for large E-ATX motherboards and long graphics cards.
- Support for multiple large radiators (up to two 420mm and one 360mm) is highly valued for custom loops.
- The included flexible GPU holder prevents graphics card sag in various orientations.
Common Complaints
- The absence of any pre-installed fans means an additional purchase is necessary.
- The integrated ARGB/PWM hubs do not allow for individual control of connected fans or lighting.
- 140mm fans can create a noticeable buzzing noise due to internal obstructions, requiring modification or spacers.
- Some users have experienced a loose front panel.
- The bottom dust filter is difficult to access for cleaning when the case is upright.
Ownership Tips
- You'll spend extra time and money picking out and installing all your fans since none are included.
- If you want detailed ARGB control for each fan, you'll need to bypass the case's hub and connect directly to the motherboard or a third-party controller.
- Be prepared to troubleshoot potential buzzing noises if you use 140mm fans, as the internal structure can interfere.
- The case is heavy at 15.3 kg, so moving it around, especially when built, is a two-person job.
- The modularity for inverted/horizontal layouts is genuinely quick to implement, not just a marketing claim.
Frequently Asked Questions
Does the Light Base 900 DX come with any fans?
No, the Light Base 900 DX Black does not include any pre-installed fans. You will need to purchase fans separately.
How many radiators can I install in this case?
You can install up to two 420mm radiators (top and bottom) and an additional 360mm radiator on the side, for a total of three radiators.
Can I control the ARGB lighting for each fan individually?
The integrated ARGB hubs send the same signal to all connected devices, so you cannot control each fan's ARGB lighting individually through the case's hub.
What is the maximum GPU length supported?
The case supports graphics cards up to 495mm in length.
Can I mount my GPU vertically?
Yes, the Light Base 900 DX includes a flexible graphics card holder that supports both horizontal and vertical GPU installations.
Buying Guide
When you're looking at a PC case like this, you're essentially buying the shell and the framework for your components. It's not just about how it looks, but how well it helps your parts breathe and how easy it is to build in. Think about your cooling plans first, because this case is designed for serious liquid cooling, but doesn't come with any fans to get you started. You're paying for the flexibility and the display potential.
Dual Chamber Design
This means the case is split into two main sections. One side is for your visible components like the motherboard and GPU, and the other side hides away the power supply, drives, and cables. This makes for a much cleaner look and can improve airflow to your main components, like having a separate 'engine room' for your PC.
E-ATX Motherboard Compatible
E-ATX motherboards are larger than standard ATX boards, often found in high-end systems with more features, RAM slots, or CPU sockets. If you're planning a powerful build that needs a bigger motherboard, this compatibility ensures it will fit without issues.
Radiator Support (e.g., 2x 420mm, 1x 360mm)
Radiators are crucial for liquid cooling, dissipating heat from your CPU and GPU. The ability to mount multiple large radiators means you can run very powerful, hot components and keep them cool, even under heavy load, similar to how a car needs a big radiator for a powerful engine.
Alternatives
If this case doesn't fit, look for cases that include pre-installed fans if you're on a tighter budget, or models with more advanced ARGB controllers for individual fan lighting customization.
