Hi, I'm about to buy a Mac Pro and would like to know how much should I pay for it... It's the first Pro with two dual core 2.66 GHz Xeons, 4 GB RAM, 250 GB HDD, superdrive, GeForce 7300 GT, Airport Extreme Card, Bluetooth and 4 months of Apple Care left. It comes with the original keyboard and mouse (I was told those were not used). I hope this is the right forum section to ask such a question... Thanks for your help.
