    I currently have a macbook pro but plan on getting a desktop mac sometime this year. My perfect computer would probably be the 'headless' mac but there's no such thing as that. I've even thought of a mac mini but I know power is limited. I ended up coming up with a Mac Pro. I don't like the idea of upgrading the iMac and then losing my monitor. I know there's a variety of processors I can use as well as other configurations. I'd likely add a 24 inch widescreen monitor to it but overall the Mac Pro does seem like overkill to me. If I get a iMac I'd likely get a medium range 20 inch model.
    My question comes down to power usage (wattage, etc). It seems with the 4 core system out now and the future 8 core mac pro's that are rumored that this is a very powerful system and although nice way more power than I need. I like the tower case where I can expand it more than the iMac but with all those cores I can't help but wonder what type of power it uses. How does the power of a Mac Pro compare to a iMac? (wattage, etc) and are there many power saving features where the mac pro could use far less than maximum if I don't use full power? I see it is considered to be a energy star computer.

    Since they conveniently leave off the toal power consumption, you can (I think) do W=AxV to get 12 x 120 = 1440 W.

    That's probably wrong, but they do list 300 W of power just for the PCI bus.
