High-quality sturdy construction, pleasant cable management, good dust filters but with difficult (compared to other cases) access. With 3 bequiet fans (not the high-speed ones) and a pure rock 2, everything at 100% is almost silent.
However, don't expect much in terms of airflow. I would say none at all. Without the front panel, the temperature dropped by 9 degrees on an RX580 and 4 degrees on an R5 3600, both under 100% synthetic load. I also tried with 2 bequiet high-speed 140mm fans at the front with the panel installed, but not much changed, I saw a difference of 1-2 degrees. The removable top panel helps if you set the exhaust upwards instead of at the back, but taking it on and off is a pain because it can only be done from inside the case and you have to be careful not to break the clips. Also, the absence of noise is a thing of the past.
However, the truth is that you get this case for its noise reduction and build quality, where it excels. Otherwise, you can go for something more affordable and/or with a mesh front.

The box is great in everything, its fans are quiet but only at their first speed level.

But there is an issue: I have a rotating disk inside and it makes incredible noise, while in the previous box it didn't. At the first opportunity, I will remove it, which I don't like at all because I have my backup inside.

edit: the front USB ports are very tight to a considerable extent. Also, when I have a USB stick connected to one front port and I try to insert a second one into the other port, the first one disconnects and starts acting up. Oh, and the indicator light that shows that the computer is working is very bright. When the computer is on standby, it flashes and I don't like it because I might just put the computer on standby to go to sleep and the light is too bright. I should mention that the disk light is also bright, but let's say it doesn't matter.

edit 19/3/21
When I plug my headphones into the front port of the box (not the motherboard), only the left one works, while directly from the motherboard both work. I don't know, maybe the cable for the headphones/speakers inside is not properly connected to the motherboard. Edit again 22/9/22: it turned out that if you insert the headphones as far as the plug goes, then they only play from one side. If you have them slightly pulled out, then they play from both sides. But the plug doesn't fit well, so if it goes in a bit better, it only plays from one side, while if it comes out a bit, the contact is lost and the sound comes out from the speakers. This doesn't happen only with these specific headphones. In the photo I uploaded, I show how deep the plug should be for it to play from both sides.

I searched for it extensively as it will stay with me for many years. I chose it over the equivalent Nanoxia case due to better placement of the front doors/buttons, more convenient dimensions, and lower price.
Silence is a key factor, as in my system there are no other fans except the 2 in the case and the CPU fan. A brief description to give you an idea:
The graphics card is a passive 1030 - unfortunately, the equivalent 1050TI costs twice as much. The rest of the system is an Ashrock B450 Pro4 motherboard, a Ryzen 2600X, 16GB RAM, an SSD, 2 HDDs + a Blu-ray RW, and a Cooler Master 550 power supply.

So, the case is well-built, simple in appearance, without windows, etc. (I mention this as an advantage). The sides are lined with sound-absorbing material, as well as the front cover that attaches with the "right" degree of difficulty. Dust filters everywhere with easy removal for cleaning. The only places it doesn't have are some small grilles at the back, but there is likely a slight air exhaust from there, as the front fan is 14cm - while the rear one is 12cm (included in the package).
At all cable routing points, the metal is covered with plastic "lips" to prevent damage. The motherboard stand is well-made, with proper labeling of the support points depending on the type. There are 3 trays for HDDs with rubber for vibration prevention, and 2 removable brackets for SSDs included in the package.
The whole "package" sits on relatively large feet with soft material to prevent vibrations. Finally, in the package, apart from the 2 good silent fans, there are several cables for 2 HDDs, external drives, etc., as well as several screws of various types.
Needless to say, the wiring that connects the front panel to... everything is very complete - among other things, there is also the cable for the 3-speed fan switch.

I assembled the system by myself without any difficulty, even though I didn't have much experience. Of course, I studied the motherboard manual and watched a video about the case online. When finished, the interior looks very organized, as the cables pass easily from the back, where with a little thought and care, you can gather and secure them. In the package, there are some special strips and several slots on the chassis for this purpose.
The few negatives: the rear screws that are supposed to open by hand don't... and they are also "painted" black, so they peel off. The plastic cover on the top (supposedly for additional ventilation) opens and closes very difficultly - I don't need it, so it remains closed, but I mention it. Finally, the power supply sits well in its place, but it doesn't have a cover (a minor flaw).

Assembled, the system shines through its absence! In an extremely quiet home environment, the only thing you can hear as a minimal whisper (if you listen closely) is the CPU fan.

Temperatures with two image editing programs open in collaboration + Firefox with 7-8 tabs + Libreoffice (memory at 70-80%), did not exceed 45-50 degrees.

For now, I am very satisfied, and in 2-3 months when I check for dust, I will come back.

edit (5/3/2019): in heavy batch processing of raw image files, the Ryzen reached peaks of 85 C, so I changed the cooler (Be quiet Shadow Rock TF2) and added another intake fan. The temperature dropped to a maximum of 69°C and the overall is even quieter than before.

edit2 (12/12/2023): Four years later, an Asus RTX1650 with active cooling (fan) has been added in between, and the Ryzen is now the 5700X. Cleaning once a year from minimal dust with a low-power blower. Quietness, order, and thoughts for a "compact" 4060 with 2 fans - the big ones don't fit.
