a little late but, for others that are willing to spend a little fortune on cases + fans +dissipators, i know that on a local store theyve got some freezer cases, like the ones they use on some research institutions... They claim you can have a P2.8 overclocked to 3.8 with those things (in fact theyll prepare one of those for you if you are willing to spend 500€ on the case... (but then you save on all those dissipators and fans) I hadnt seen em on internet but maybe you would be interested on asking for them on your local dealer...
