Don't consider Thermaltake.
The PC7 is the most case per £ you will get as noni has said, just looks a little bland, but is a lot better in person.
The V series is the same, just a bit more expensive; needs a bit of patience (hour of your time usually) to get the best cooling for your rig.
Akasa Eclipse, if this case can't cool your rig, nothing can.

You have to remmember that any case can cool almost any rig, its the quality and easy of use that make them different.
Low noise cases are a gimmic in my opinion, if your components are noisey in one case, they will be in another. Having used all of the quiet cases, all are noisier than my V1000+ is at the moment, with the same system in.
Figure that one out
