Watch Out For

What Buyers Say
This case is a dream for builders wanting to show off their components, with its panoramic glass and clean aesthetic. The dual-chamber design really does make cable management a breeze, and it handles serious cooling setups, including dual 420mm radiators. However, the fan count in the product title is misleading, as it only includes 3 RGB fans, not 7. Building with standard motherboards also means sacrificing some of the clean look due to cable routing.
“Dude, this case is gorgeous, but seriously, why did they say 7 fans when it only came with 3? Still, my 4090 fits with room to spare and temps are chill.”
Common Praise
- It's very easy to build in.
- The finished build ends up looking really nice.
- It cools really well and effectively.
- The case runs quietly.
- There's lots of rear space for cable management.
- It has room for the largest GPUs and two 420mm AIOs.
Common Complaints
- The product title claims 7 RGB fans, but only 3 RGB fans are included.
- Using a standard motherboard requires removing a cover, which affects the clean aesthetic.
- The included fans are 3-pin DC, limiting precise speed control compared to PWM.
- Its large size (12.4 inches wide) might be too big for some desk setups.
Ownership Tips
- The panoramic glass panels are a fingerprint magnet, requiring frequent cleaning to maintain the aesthetic.
- The weight of the case (444.45 ounces or 27.78 lbs) makes it difficult to move once fully built.
- The angled front-right fans genuinely improve airflow to the GPU, keeping temperatures lower than expected.
- The NZXT Control Hub is convenient for managing the included RGB fans, but adding more fans might require additional controllers.

Buying Guide
When picking a PC case, you're balancing how much space you need for your parts, how well it keeps things cool, and how it looks. For a case like this, the 'dual-chamber' design means your power supply and hard drives are hidden away, making your main components look super clean and helping air flow better. 'Radiator support' tells you how big of a liquid cooler you can fit, which is key for high-end CPUs.
