Two things,

For the technical aspects, I've got a heavycoin hardware comparison wiki going at http://heavycoin.wikia.com/wiki/Hardware_Comparison that might be useful when comparing efficiency and wattages. I think we have a real advantage with nVidia cards for HVC.

Second, the @HeavycoinNews feed is just... Broken. Getting spammed in the most annoying ways. It needs someone actively watching it.

Good luck giving HVC a second wind!
