Customers are mixed about the instructions. Some mention that it wasn't hard to do, and was fun taking a part and putting back together. They say the built in cable management is decent, and the case is easy to work with. However, others say that there are no instructions, the manual could be a little better, and it could be tricky to assemble this case. The modularity of the case makes the assembly a bit confusing.

Customers are mixed about the air flow. Some mention that the airflow is great and everything stays very cool, while others say that the fans are silent and the air is terrible. They feel that the outer layers would hinder airflow and that there is no proper ventilation on top.

Customers are mixed about the cooling of the computer chassis. Some mention that the airflow is great and everything stays very cool, with slight noise but no overheat. The build quality is superb, and the temps are fine. However, others say that the heat saturation is bad, even with all 7 fans running high. The case has a very hard time shedding heat, and it's not well setup for liquid cooling.

"The Beast" wallops the words flexibility and spaciousness
The beast has so much room that even fat fingered, eye glass wearing guy like me could get in there and perform detailed cable management. The motherboard tray slides out of its rail so you can mount your gear outside the case and slide it all back in with ease. The same goes with the radiator attachment at the top. I've mounted 5 140 mm fans and 3 120 mm radiator fans. I still have room for another 3 120 mm fans. (and I've just ordered the BQ Light Wings). The case has noise dampening panels if you want quiet or mesh panels for extreme air flow. It's big and sturdy. The case quick start guide is garbage but then again, all Be Quiet manuals are. There are too many features to highlight in a short review. It's expensive but it will really show off your build.

5.0 out of 5 stars Quality Case, Lots of Options
Reviewed in the United States on October 27, 2023
Great case. Plenty of room for the very thick Arctic Freezer II 360 AIO which is a huge plus. The case comes with 2 140 fans on the front and 1 in the back. You can add another 140 so long as you don't use the 5.25" drive bay. I wanted to use it, so was limited to adding an additional 120mm fan in the front which just barely fit. I like the 5.25 drive bay option and is one of the reasons I chose this case. I opted for a hot swap drive bay but would have liked a second for an optical drive. Oh well.

You'll notice the GPU support isn't covering the cable as intended. I think the support would bend the cable too hard and perhaps break connections. I'm not willing to take that chance. Also, a GPU with 3 fans doesn't provide many options for placement. I will be buying a different GPU support and removing the provide support, which is a shame because the Be Quiet support looks better. .
 
There are so many options with this case that it almost seems like a waste. I have lots of pieces that are not going to be used, and these add to the cost. But I still chose this case so perhaps they have the right price/options blend.

Summary: a large, well-constructed case with options for every build type. Would have liked a gromet on the back of the case, a reset button on the front and some additional SSD mounting options, but still well worth the price.
