Thanks Erik. I am not really interested in buying Wintel hardware to save a few bucks. I also would prefer having the ability to keep all my drives and hardware compatible if I need to take one of the slaves off the render and use it for production on something else. I have also heard that AE is still optimized for the G4. Thats why I ask if the G4s would be worth anything.
As far as Nucleo goes, I already use it. I think it works well in many circumstances. Nucleo Pro sounds even better but I would rather push this off other machines and keep the workstations working on designing and animating.
I was thinking of buying a couple DP 2.5 G5s – just some refurb models – and putting in 4GB of RAM in each of them. I could start off smaller on the RAM. Would it be more beneficial to build an XServe renderfarm or is that really overkill for the money?
