Ah mac, the pricing is totally out of whack.
Same mobo on all the units, just the low-end unit is running @ 133Mhz because of the clock multiplier.
For the money I want to spend, adding the SuperDrive to the low-end unit, I think the 17" iMac does it for me...
As usual, a total let-down in speeds from Apple. I hope they ditch MOTO, they are sinking us.
