Very nice case!
I just got the Anidees AI Crystal case (which in my understanding is what Rosewill rebadged to make the Cullinan). I brought it to MAGFest and it got a lot of attention for how it looks. It has a lot of similarities to this case, but also has smoked glass on the other side and the front. EXTREMELY heavy lol... It also has room/vents for a 360 radiator up top and in front.
I'm extremely pleased with the aesthetics and workmanship, but the space for cables behind the motherboard is way too tight, that you almost feel like the glass will shatter.
If that's a problem for you, and you only have a small AIO liquid cooler then this NZXT case looks like a premium pick.
