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 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.

with two hard drives, 3 SSDs, an NVME stick, 3 fans,
and an aggressive air CPU cooler for an i7 13 gen. It's solid, spacious,
and the front ports work well. It comes with two 5.25 inch
bays - would have preferred three. But this is a first
class, well-built case, a superb value.
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.

The case is incredibly modular.
1) You can choose to have a mesh/grate front or a sleek aluminum panel. The same is true for the top - you can have sound dampening panels or open mesh. So, you control noise levels and airflow.
2) Every side of the case can be easily removed to work in it. You can get down to little more than the frame.
3) The side vent can be configured to be closed or open. And, you can have storage drives there or fans. HOWEVER, it does require you to choose between storage drives or fans in that side vent location. I would've liked if you could mix and match.
4) The motherboard and PCI slots is one big removable unit, making installing parts to MB as easy as an open bench. It's so wonderful!
The case provides great cable hiding covers next to motherboard. It has a GPU support bracket that also hides the power cables. It's beautiful.
The case has thicker than normal cable management section (though not huge), providing you good space to run cables.
In cooling-centric config (I haven't tried sound blocking setup), the airflow is great and everything stays very cool. GPU idles in mid 20C. My GPU will auto-overclock about 200-300MHz at 100% before hitting thermal throttling. AMD 5950x idles in mid 40C with Ice Giant Pro Siphon. This is all aircooled. I can encode long video with all 16 cores running at 4.5GHz, and it stays under 70C.
The case has a wireless phone charger on top, and I just think that's cool.
The case still supports 5.25" bay. This is a nice option that is elegantly hidden.
ONE OF THE BEST FEATURES: The case has contacts built into the case frame that align with pins on the removable top and removable front. So, you can just connect your fans to the front and top pieces with those pieces completely separated from the case, making install a breeze. Once you attach the front and top back to the case, the pins meet the contacts and all those contacts feed into a single fan header that you just plug into your motherboard. This greatly reduces the amount of wiring that you have running everywhere.
CON
(Please read all - I found a solution for me though it looks really bad at first) I had a severe issue where my GPU (EVGA 3080Ti FTW3 ULTRA), motherboard (X570 Steel Legend), and case combination prevent me from plugging in my displayport cables unless I don't screw in my GPU and let it sag. Basically, the displayport slots in the GPU were elevated so high that the cables were blocked by the case. I contacted "be quiet!" support and got a QUICK reply from them. They said 1 other person in all of USA had reported this issue, and they had no known workaround. So, they suggested I return and replace. I did that and had the same problem on the next case that was sent (maybe it was a bad batch from the same plant and distribution center). Anyway, I found a low profile, ultra thin displayport cable on Amazon that actually squeezed in and I'm all good now. I'm linking to that displayport cable below in case anyone reading this has same issue.

I absolutely recommend the case. It's looks great complimented with "be quiet!" Lightwings in the front and on the side.
If you've never built a computer before, and are considering this case, I recommend it highly. It's very easy to build in, it comes with a very nice feature on the top of the case. (Where you connect either exhaust fans, or a cooling radiator, it has a "Panel" that slides out, allowing you to install the fans outside of the case, then you simply slide the panel with the fans installed back in. A hundred times easier than trying to install fans directly into the case, or having to remove a bunch of panels to install them.
If you have built computers before, you'll probably appreciate the cable management system, the included fan/RGB controller, the neatness of PSU shroud (Which also allows for a single 140/120mm intake fan on the shroud it'self.) Once it's put together it's extremely clean looking. It also was designed well, and you can easily fit a 360mm Radiator in the front while still using the PSU Shroud, and an intake fan on the bottom.
It also comes with 2 full slide-out Air Filters. No tools required to remove and clean them either. Everything was extremely well thought out.
There is only one or two things that could be improved on, honestly.. But they aren't a big deal.
