Quiet Case That Can Deal With Heat Problems

Right now, I've got everything inside an Antec 900 and am having some heat issues with the graphics card that, in addition to making me feel slightly uncomfortable, also necessitate running the fans on high, which is pretty noisy (case fans can't be controlled by mobo and can't be reasonably adjusted manually at different times).

My current specs:
Gigabyte X58A-UD3R mobo
i7 930 at 2.8 GHz
Thermalright U120 cooler (sticks out rather far, prevented installation of side fan in current case)
6 GB G.SKILL DDR3 (3x2)
Silverstone 750W PSU
Deskstar 1TB SATA
one DVD drive
Gigabye GTX 470

The i7 is fine with heat (typically sits at low 30s, gets up to around 40C under load). The GTX 470 is absolutely ludicrous, idling at around 30C, but very quickly hitting about 93C when playing more or less any modern game (I haven't ever even tried benchmarking for heat). My understanding is that this is within the safe range for the card, but I would love to see it at least a bit cooler if possible, if only to prevent it from turning the room into a sauna  

Additionally, I'm not a fan of the look of the 900 at all (got it from a friend when I first put the build together about a year ago). I'd rather find something a little more sleek and sexy without all of the molded plastic, lights, and window. On the other hand, I'm not entirely in love with the large metal brick design either (though it's very preferable to the former). Although it's a bit on the expensive side (understandment) the ThermalTake Level 10 looks somewhat attractive, though I definitely worry about how it would do cooling compared to the 900 that's already not doing so incredibly well.

So, any suggestions for cases (with fan suggestions or any other suggestions regarding noise/cooling would be phenomenal)?

Edit: Not looking to overclock at all (haven't really had any need to do so, so I don't really have any desire to go through the hassle).
