Hello Don, I bought such an instrument to measure the power consumption (sorry, I didn't find the correct english expression). That was not to expensice (about 20 $ in germany, over here there are even special local offices with energy advisers and there one can lend such an instrument for free) So I compared my machines. The cube I used before my Mac mini spent a lot (as I remember). Finally I used a TFT with DVI-Port and shut down that monitor. If you are interested I could repeat that (I've a Cube with Gigadesigns 1.5 GHz, max RAM, max HD, 9200 Radeon, as far as I remember. Tell me if I should measure. But I believe, there is no power lead to the ADC-Monitor when the cube is sleeping. My Mac mini on the other hand only needs 2 Watt sleeping and about 50 Watt idle. The TFT is another story. TFTs need much less power, when dimmed. And modern TFTs are normaly dimmed nearly to 0% of their brightness. My Dell is bright enough with 0% brightness. Energy comsumption is up to 180 Watt with full brightness, but only about 70 Watt at minimal brightness. There's a huge difference. (I didn't measure that in this case, I read it about my model in a review. Maybe I should proof it my own) Unfortunately the CRTs need nearly full power all the time. Hope I could give some hints (?)
