Dimension Scores

Efficiency & Output8/10

Supports up to 10 fans and three large radiators (two 420mm, one 360mm), providing extensive cooling potential for high-performance builds.

Noise Level7/10

Comes with 4 Light Wings 140mm PWM fans designed for quiet operation, with user reports indicating quiet performance at 50% fan speed.

Build Quality8/10

Constructed from alloy steel with tempered glass panels, described by users as feeling 'solid' and 'premium' despite its weight.

Cable Management6/10

Features a dual-chamber design for cable routing, but the rear chamber can become tight with a large PSU and numerous drives.

Best For

  • Enthusiasts wanting to display their PC components with extensive ARGB lighting.
  • Builds requiring maximum liquid cooling capacity with multiple large radiators.
  • Users needing flexible case orientation (standard, inverted, horizontal) for specific desk setups.
  • Systems with large E-ATX motherboards and long, heavy graphics cards.

Not Recommended For

  • Space-constrained desk setups due to its large footprint.
  • Budget-conscious builders, as it's a mid-range to high-end case.
  • Users prioritizing maximum direct front airflow over aesthetic window panels.

Watch Out For

  • Reverse-blade 140mm Light Wings fans are not sold separately by be quiet!, making it difficult to maintain a consistent look if more are needed.
  • The rear chamber for cable management can feel constrained when using a large power supply and many cables.
  • The all-glass front panel means no direct front fan mounting, potentially impacting airflow strategy for some users.
  • The case's 16.8 kg weight makes it challenging to move frequently.

What Buyers Say

Users are drawn to this case for its panoramic glass panels and extensive ARGB lighting, making it a centerpiece for showing off components. The flexible layout options, particularly the ability to invert or go horizontal, are frequently highlighted as a unique selling point. While cooling potential is praised due to its radiator support and included fans, some builders note the rear cable management area can get cramped. The sheer size and weight are also recurring points of discussion.

“Man, this case is HUGE but my build looks absolutely insane in it, the ARGB strip is brighter than my future and I can finally show off my 4090 without it looking like it's gonna fall out. Cable management was a bit of a wrestle though, not gonna lie.”

Common Praise

  • Fully windowed design provides an unobstructed view of internal components.
  • ARGB lighting strip with 172 LEDs and motherboard sync creates a visually striking build.
  • Easy conversion to inverted or horizontal layouts offers significant placement flexibility.
  • Ample space for E-ATX motherboards, long GPUs (up to 495mm), and multiple large radiators.
  • Included Light Wings 140mm PWM fans provide effective and quiet airflow.
  • Integrated VGA holder prevents GPU sag in any orientation.

Common Complaints

  • The rear cable management area can be tight, especially with a large power supply and many cables.
  • The case is very large and heavy (16.8 kg), making it difficult to handle or move.
  • Reverse-blade fans are not available for separate purchase, limiting aesthetic consistency for additional fans.
  • The all-glass front panel prevents direct front fan mounting, which some users prefer for airflow.

Ownership Tips

  • The included ARGB hub simplifies connecting and synchronizing multiple lighting elements.
  • The removable radiator/fan holders in the lid and base simplify liquid cooling installation.
  • Dust filters on mesh panels are easily removable for cleaning.
  • The case supports motherboards with backside connector designs.

Buying Guide

When picking a PC case like this, you're not just getting a box for your parts; you're getting a display case. The size matters a lot for where it'll sit, and how much glass it has dictates how much of your build you'll see. Think about your cooling plans too – if you're going all out with liquid cooling, radiator support is key.

Dual Chamber Design

This means the case is split into two main sections. One side is for your motherboard and visible components, and the other hides your power supply, drives, and cables, making for a cleaner look.

E-ATX Motherboard Compatible

This indicates the case can fit larger motherboards than standard ATX, which is important if you're planning a high-end build with more features or expansion slots.

Inverted and Horizontal Layout

This isn't just for looks; it changes how airflow works and how your components are positioned, which can be crucial for specific desk setups or cooling strategies.

Radiator Support (e.g., 420mm)

This number tells you the maximum size of liquid cooling radiators the case can accommodate. Larger numbers mean more cooling potential, essential for powerful CPUs and GPUs.

Alternatives

If this case is too large or too focused on aesthetics, look for cases with smaller footprints, more direct front airflow options via mesh panels, or models without pre-installed fans for a lower initial cost.
