I can't recommend the Parvum case highly enough. They're so beautiful, a pleasure to work with, and the guys at Parvum are always happy to help if you run into difficulties. And they're so freaking beautiful.
The acrylic is perfectly sturdy. I'm not sure what you would have to do to damage it that wouldn't also damage a Prodigy. And because the case comes in pieces, if you do damage part of it you can just have that panel replaced rather than buying a whole new case.
In theory, having the h100 as an intake would give better CPU temps as the radiator is getting cooler air. On the down side, you'd get better air flow with normal fans as intake and the h100 as exhaust.
I'm not sure it really makes much difference in practice. I put mine in the front because I thought it looked better.
