Glass Panes do not stay Flushed
Overall, I love the design and aesthetic of this case, and it was super easy to build in. It looks great, has plenty of room for fans and large GPU's and tons of space in the back for all the cables with a great location for the PSU.
The only thing taking stars off this review is that the glass panels do not stay flushed with a pretty sizeable gap on my build which is just jarring every time I look at it and not something I would expect for such a premium product especially at this price point. If I look head on at the product you cannot notice the gap because of where it is, but as the PC is to the side I can always see it, and it is extremely noticeable and disappointing. If it were not for the very large gap between the panels this would be a 5-star product.

The "Waaaaiting is The Hardest Part".
Right now it is unpacked and is sitting on my desk waiting for all the other pieces to arrive, but it looks GREAT! The build quality is excellent. Lots of room. Even the top panel comes off! I should be able to access anything. This is my second NZXT case - the first one is almost 10 years old. Can't wait to see the new one filled with LIGHT and ENERGY! I'm 72 and enjoying learning about things like ARGB, M.2 storage, CPU coolers and all the rest. You can teach an old IT guy new tricks!
