All depends on what you want to spend...
I've a Coolermaster Centurion 5, which is a very nice case. About €60. http://www.coolermaster.com/products/product.php?act=detail&tbcate=17&id=21
If the sky's the limit there's always the Zalman TNN300, at about €600.
Neither comes with a powersupply btw. Matching supplies may cost several hundred more depending on the model you choose (and for the Zalman there's only one model to choose from, I think their 850W heatpipe PSU but a Zalman dealer would know for sure).
