The rough idea is to use strategically placed vents and a chimney to 'enhance' convection. About the shape, think of how fireplace chimneys work... Yep that kind of 'exponential' shape would do it.
(edit) i'm still convinved that the case itself is part of the solution there. A custom-built one sounds like a good idea.

Thnx. Haven't found anything yet, but I get the idea. Actually, I could enhance the chimney by heating the air in the upper part of it. The heat wouldn't get to the case, but would increase the airflow. It just seems a bit waste of energy. Maybe I do need to build my own case. It's a pity some people don't get the idea of silence and zero fan. I'm afraid I'm beyond quiet undervolted fans, blowholes and wrapping up harddrives. I already have all that, and I want to move on. Somehow I don't get it that a 20 year old calculator has less moving parts then a modern pc and is less noisy, and that they call that progress. To me all this feels like you need a steam engine to keep your 2 GHz processor running. I'm able to sleep next to my alarm clock/radio (until it goes of), so why wouldn't I do that next to my computer? Would anybody accept a photo camera that's buzzing and whining all the time? Or a light bulb that doubles up as a gas turbine? But a computer that whines, buzzes and rattles is appearantly perfectly acceptable. And when someone gets that down to the level of a vacuum cleaner at half voltage, it's called a quiet computer. No way! Nothing in a computer that's essential to computing is actually making noise or even moving, so it must be possible to make a noiseless computer. And maybe I will do that, just for the hell of it.
Oops, this turns into a quest against sound and I didn't mean that. I do like music. But I like to listen to it not disturbed by the sound of a computer. Why else would there be mp3?
