Thanks for everyones input it is very much appreciated.

I will take the advice and make a generic scene and than do multiple versions and get opinions of which way to go.

All my PC's are on APC UPS Units so no worries about brown outs or powerloss.

I will be using 4 Systems that will be doing the core of the rendering.  2 x Single Core CPU's @ 2Ghz each with 2GB and 3GB of Ram. and 2 x 2 Core CPU's @ 2Ghz and 2GB of RAM Each.

A 5th PC (Slowest) will be used to delegate the actual render job since  the Latest version of Bryce does not Render when but only acts as a Server.

Bryce Lightning does not utilize 2 Core systems, so I may do some sort of Bryce/Carrara Hybrid.
