bit-tech.net | has some nice pics of a new case offering from Cooler Master. The
HAF 932 looks like a wildly flexible box of tricks. Five of the six sides have multiple fan mounts and more holes than swish cheese. You can put the PS on the top or the bottom and the knockout that covers the hole you are not using has convenient holes for WC tubing. I think this is a great idea. It even gives options for the folks who want to jam two mainboards in one case.
I wonder if a 2x120 rad could be attached to that top grill or the side grill and properly fanned. I also wonder if you can buy spare right side plates to replace the like Antec does
