I am glad to hear that you are planning to try out Morphos. I just hope you are not dissapointed due to the emac's shortcomings, there is already a thread on making on head-less Emac on another forum. I would try to track down a G4 Powermac and given that you are in Philadelphia - you will not have a hard time nabbing a good deal on craigslist with a few days of patience.
Then again.... talk this guy down and you have a steal.....
