I got mine yesterday and spent 2 and a half hours putting it together...
It is not easy (coming from a P160) since it's not tool less. Lots of screws to take out. No rubber mounts for any drives. It can fit 6 hard drives and 3 dvd drives so the room is not a problem but mounting the drives is a P.I.T.A.
The window is pretty flimsy (compared to the P160) but you can mount a fan on it. There is a bracket on the window that cannot be removed. It was an issue with my Thermaltake Silent Water being mounted to the rear 120mm. I had to put my Silent Water on top of the bottom mounted drive cage which took away 3 hard drive spots and 1 DVD/CD drive spot...
Also, my PSU had to be mounted with the fan facing up which puts the wires closest to the window and kind of junked up my wiring...
All in all, I'm sure this case has excellent cooling and it looks cool but it's not the most user friendly case... Not worth more than $100 IMHO.
I kept looking back at my P160 and almost said screw this... I liked the room of the P160 and it's user friendliness...
