Nice rig. Personally (my own opinion) I don't like the Antec Nine Hundred case. It looks ugly compared to the P-180 and P-150.
Kinda cool how it has all those fans, but just more ambient noise I don't need. The 200mm fan on the top may be nice, but good luck replacing it. I'm sure the construction is really good though, on par with Antec's normal quality. I love how the top looks like an armrest from a pickup truck.
Haha, anyways...nice rig.
