I've had this case for 6 months and have to say it is, by far, the best case I've ever had and I've been building PCs for decades. It's silent, but more importantly, the air exiting the case is always cool, never hot and this is a first for me. I have a 4090 Supreme liquid AOI on the top of the case, right BESIDE my Liquid Frozen 360. I've never had a case where both AIOs sit side by side on the top of the case even though the case doesn't appear to be wide, like other cases. I was initially concerned about the size, but it fits just fine under my desk and is pretty much like a regular full size tower case.
The case is really well thought out and the best part is the airflow, large fans run slow and silent. Two exit fans are great!
The only issue I have with the case is putting the side panels on when you take them off, they are tricky and could use a re-work.
Otherwise, highly, highly recommend this case if you want airflow, options for mounting coolers, lots of room and most importantly, cool airflow.
I just checked mine and the long skinny vent at the back of the case right above the PSU (where the plug goes), is cool, the air coming out of it is cool. The two openings on the side of the case are really well done, the one where the PSU is, is large enough for airflow and they are stylish too, meaning they are not just a straight vent, they have a good look to them. I have a 1K PSU and it doesn't heat up.
The lack of dust filters, I don't know what to say, there is no dust in my case and the filters that go over the vents are removable, they look like any of the other filters these days. My case is on the floor, so it would attract dust, but the case is clean.
