First things first. I like it. I like it a lot.
That being said I do thing there are a few things that could use some tweaking.
First and simplest. Thous SSD mounts are just screaming to have some sort of trim piece when not in use. A simple little piece of plastic that can be put in instead of the cage would be all it takes. They are really nice looking when in use but if you only have 1 or no SSD its looks really off.
The ability to fit a 360 radiator in the front is brilliant. What would be even greater would be if after doing that you sill had some place to stick a HDD. Lets face it most of us can make due with just SSD's. I think there would have been enough room to include a HDD mount somewhere in the bottom or around the PSU.
Then there is the total lack of 5.25 bays. I'm kinda on the fence about this. At one hand I totally get why they where removed. The aesthetics, airflow and general layout is really nice with out them but I even if you don't use opticals there is still other uses for them like fan controllers and bay reservoirs. It would have been nice if there was some way to mount an 5.25 like ripping out one of the front fans and sticking in a 5.25 cage or something. I would't even mind if you could not get to the bays with the front panel on. I just think people like me will have a hard time giving up their 5.25 hardware.
But thees are all minor flaws at best and it is really nice case
