MacPro, MacBook Pro or iMac for ideal/flexible DP setup?

[sdemott]

My latest thought on cutting the initial outlay:

Is it possible to connect a MacPro to an iMac to use the iMac as the monitor, thus forestalling the $600-$1000+ purchase of a standalone monitor?

I have the 15" 800 MHz G4 model. There are a couple of connectors on the back that don't make sense to me, so maybe they're for monitor connections (though probably only for an external monitor for the iMac -- and I know for certain mhy model does not support dual monitor mode for drag/drop; just a "copy" of thge main screen on another screen).

I have a feeling this is another of those connections that goes "the wrong way"; like the ADAT connection on the Receptor .

The iMac won't take a video in signal - it only sends it out...so that's not an option. But the good news is that a good monitor will last through several computer upgrades. They don't become obsolete nearly as fast as the computers themselves.
