Purchase at 150€. I have worked with the case for a few hours and the following comments are about my experience so far.
First of all, I have to say that the reason I changed the case (NZXT S340 for 4-5 years) is mostly due to the airflow. Recently, I installed a 240mm liquid cooler in the front of the NZXT case and upgraded to a 1080 Ti. The case, not having the best airflow on the market along with the radiator in the front, did not bring in much cold air, resulting in the card reaching 83c (!) under gaming conditions. I knew that this particular card requires a lot of power, but the temperatures were too high for my liking.
I had seen many cases since before every purchase I really search the entire Internet, I had ended up with the H500M, the PC-O11 Dynamic, and the P600s. Money didn't interest me much since I had the patience and the ability to buy something good that would last for years, and this time beauty would not be the only criterion as it was when I bought the S340. So, rejecting the first two, I ended up with the Phanteks and I can only say positive things.
Build quality? Space? Airflow? Everything, absolutely everything, is perfect. There has been tremendous research in every aspect of the case and this is evident from the first few minutes of working with it. Everything is where it should be, there is plenty of space for everything (to the point where I closed the back panel with just one finger without needing to do any special cable management), solid construction, soundproofing material in specific parts. The case is truly a transformer, you can adjust it exactly as you want, whether it's for silence or airflow.
In specific games, I saw up to 10c (!) lower temperatures compared to the previous case, now I really see the temperatures that I saw in reviews on open test benches inside the case with closed panels!
The filters are also extremely well-textured, I don't know how well they do their job since it's too early to have an opinion.
Everything is perfect, guys, I honestly can't find anything negative. It's quite large and bulky, but it's a jewel on the desk. Hopefully, everything will go smoothly in terms of dust as well.
Buy without fear, congratulations to Phanteks for managing to release such a gem in the market! I don't think there is a rival at 150€!
