The air-tunnel thing seems of questionable benefit to me: wouldn't some hot air get trapped around the VRM?
In my opinion, back-to-front airflow with a side fan exhausting hot air from both CPU and GPU would be a better idea. Bonus points for removing the rear grill altogether, since a standalone one could be
better for both noise and performance.
And a few questions, if I may:
1. Is there a way to use the case in the classic, non-inverted layout?
2. Are there going to be solid and/or glass panels available as an option?
3. What is the front-panel USB bandwidth?
4. Still no steel threaded inserts? :/
