At first I thought "wow, easy so much space", yeah there might be enough space in the front - however cable management in the back was a pain. I already have a modular power supply and only used 3 out of 4 modular cables but still I had trouble closing the back.
The HDD area is anoying: If you screw the HDD into the cage you actually need to apply a little bit of force when sliding it in since its ~1mm too wide with the screw. When I put in the SATA-Power connector into one of the HDD's there is at best ~1mm space between it and the back wall - so its all pretty tight fit but this is something I am used to (I've never worked with a case worth more than ~40€).
Airflow seems to be way better than my Sharkoon VG5-V though.
I kind of rushed the build today since the new season in league of legends began and I want to play but I will make it look pretty this weekend to make some photos. (There are still 1-2 cables in the front that I could hide better)
If they ever release another version of this case I wish they would add a back wall like this to give a little bit more room for cables:

EDIT: didn't read all posts before answering - Yes the radiator of my AORUS Liquid Cooler 240 fit perfectly. The radiator is kind of thin tho, so if anyone of you has thicker radiators it could be very tight.
