Pros
- The FRAME modular system allows swapping panels and upgrading motherboard trays for extensive customization.
- The InfiniRail system mounts fans up to 200mm (front) and 140mm (roof) anywhere on rails, not fixed slots.
- Supports dual 360mm radiators in front, roof, and side positions for extensive cooling.
- Includes three daisy-chainable CORSAIR RS PWM fans with Zero RPM mode for quiet operation at low loads.
- Compatible with reverse connector motherboards for cleaner, hidden cable builds.
- An internal side panel can be used as a cable cover or to mount additional fans for increased cooling.
Cons
- No rear exhaust fan is included, despite three front intake fans, potentially leading to unbalanced airflow out of the box.
- Front I/O ports are located at the bottom of the case, which is inconvenient for floor setups.
- The included GPU anti-sag bracket may not reach shorter GPUs or can block motherboard ports.
- Some steel panels are described as "somewhat flimsy" by one review.
- The top handle is prone to breaking if used to lift the case, with no physical warning in the box.
Dimension Scores
Designed for high airflow with a 3D Y-pattern front panel, supports up to 12x 120mm fans, and dual 360mm radiators.
The included CORSAIR RS PWM fans support Zero RPM mode for near-silent operation at low loads.
Features tempered glass and captive thumbscrews, but some steel panels are described as 'somewhat flimsy' and the top handle is a known weak point.
Offers an internal side panel for cable cover, ample tie-downs, velcro straps, and is designed for reverse connector motherboards.
Best For
- PC builders wanting extensive cooling options with up to 12x 120mm fans or dual 360mm radiators.
- Users planning a clean build with a reverse connector motherboard.
- Enthusiasts who want to customize their case components over time with the FRAME system.
- Desk setups where bottom-mounted front I/O is easily accessible.
Not Recommended For
- Users who need a compact mid-tower, as it's slightly larger than previous 4000D models.
- Builders who place their PC on the floor and need easy access to top or front I/O.
- Anyone expecting a pre-configured exhaust fan for balanced airflow out of the box.
Watch Out For
- The top handle is flimsy and can break if used to lift the case, risking damage to the PC.
- The included GPU anti-sag bracket might not extend far enough for triple-fan GPUs or can interfere with motherboard USB 3 ports.
- Front I/O ports are located at the bottom of the case, making them awkward to access if the case is on the floor.
- No physical manual is included, only a QR code, which means critical warnings like the handle's fragility might be missed.
- The front panel's InfiniRail fan mounting system requires removing the front feet and a screwed-in panel to adjust, which can be a chore.

What Buyers Say
Builders are finding the case's top handle to be a significant design flaw, prone to breaking if used to lift the system, which is not clearly warned about in the box. Despite this, the case is praised for its extensive cooling capabilities, including support for dual 360mm radiators and flexible fan mounting with the InfiniRail system. The modular FRAME system and compatibility with reverse connector motherboards are also frequently highlighted for simplifying builds and offering customization.
“Dude, this case looks sick and the airflow is insane, but seriously, DO NOT use that top handle, it snapped right off and almost dropped my whole rig. They should put a sticker on it or something!”
Common Praise
- InfiniRail system allows flexible placement of fans up to 200mm.
- Supports dual 360mm radiators in multiple locations.
- Designed for reverse connector motherboards, making cable routing cleaner.
- Captive PSU thumbscrews prevent losing screws during assembly.
- Y-pattern front panel provides unrestricted airflow.
- Internal side panel can be used to hide cables or mount additional fans.
Common Complaints
- The top handle is flimsy and can break, risking damage to the PC.
- No rear exhaust fan is included, only three front intake fans.
- Front I/O ports are at the bottom, which is inconvenient for cases placed on the floor.
- The GPU anti-sag bracket may not align with all GPU lengths or can block motherboard ports.
- Lack of a physical manual means users might miss important warnings.
Ownership Tips
- The InfiniRail system for front fans requires removing the front feet and a screwed-in panel to adjust, which is more involved than expected.
- The bottom front I/O is actually convenient if your PC is on a desk, but a pain if it's on the floor.
- Even with the three included fans, adding a rear exhaust fan significantly improves thermal balance.
- The modularity of the FRAME system feels more like future potential than immediate utility for most builders.

Buying Guide
When picking a PC case, you're essentially choosing the home for all your expensive components. Airflow is crucial for keeping everything cool, especially if you're running powerful hardware. Cable management isn't just about aesthetics; it also helps with airflow and makes future upgrades easier. Modularity can extend the life of your case by allowing it to adapt to new hardware or preferences.
Cooling Method (Air)
This tells you the primary way the case moves heat out. 'Air' means it relies on fans to push air through the case, requiring good fan placement and unrestricted pathways to be effective.
InfiniRail™ Fan Mounting System
This isn't just about how many fans; it's about *where* you can put them. Instead of fixed screw holes, rails let you slide fans around, like adjustable shelving, for precise airflow targeting.
Reverse Connector Motherboard Compatible
This is a newer feature that means the case is designed to work with motherboards where power and data connectors are on the back, hiding cables completely for a super clean interior.
Modular
Think of this like LEGOs for your PC case. 'Modular' means parts of the case can be removed, swapped, or upgraded, giving you more flexibility than a traditional fixed chassis.
Alternatives
If this case's bottom front I/O or the handle issue is a dealbreaker, look for cases with top-mounted front I/O and solid, fixed top panels. If you need a smaller footprint, search for cases with 'micro-ATX' or 'mini-ITX' compatibility.
