They start at $500. I'm not buying one, though, because they are only available as G4s and with the G5 now available, I'd prefer to pay the extra to have the better processor. Once I've updated the upper echelon model (starting at $600) with all the extras I need (4x SuperDrive, 512 MB RAM, Airport Extreme Card, keyboard/mouse combo, and the protection plan), the total price comes up to $1,060. Then I still have to buy a monitor on top of that. There's a couple hundred more. May as well just fork out the extra few hundred and get the G5 iMac.

But for new Macheads, this is great. No question.

Here's a spec page from Apple.com.
