Rhinox,
Please equip your flameproof suit ASAP

I think without a doubt there is no reason to suggest a G4, let alone a duel g4.
First of all he said he wanted to build it himself.
Second of all one would assume he cares about saving money as in his first post he set a $1500 limit which the standard value single processor g4 system is priced around. Any apple system is overpriced for what you get when compared to a conventional pc. For example, even one of the midrange G4's that is in the pricerange of a 1ghz major pc vendors (dell,hp,compaq) system still comes with 64mb of ram, wtf?
Next is the fact that whatever gains you may get from software optimizations in adobe software for the mac platform are vastly overestimated by mac zealots and only come into play with a few select filters. Lastly is the fact that if you plan on doing any game playing at all or don't want to worry if there is a mac version of your favorite software, you should go with a pc system.
Sorry but I thought that my response deserved its own message
