I like the way it sounds.
I know the cube has been done to death and so many of them have been very beautiful as well. But, I'd still like to see a mod as close to an ice cube as you can get. I've used a two part resin that pours fairly clear and hardens in a pretty short time. I think just pour the stuff into a mold made of a cardboard box and lined with a release agent (or wax paper, etc. whatever a tests turn out as the best idea. Cooled all by just a single rear fan. I think the beauty, simplicity and low noise level of the unit could make it quite attractive.
