Wow, that's a whole lot of awesome features on that thing but honestly the thing that first jumped out at me was the Modular HDD cages... I do love modular stuff. Still this is a pretty awesome looking case, I'll definitely be looking at it for my next system build.
Its a toss-up between the 25cm fan (yeah, cool and quiet thing that spins yet barely makes a sound) and the cable management and cooler holes. How many of us have had to remove the whole mobo just to replace a cooler?
Although with that big ass fan, passive cooling would be a lot easier lol.
