Colorburst Overdrive 2 A 64-bit Rip Server For Mac

We ordered a HP 260 Latex and a separate cutter.
Caldera appears to be a 64 bit RIP so looks like it should use all RAM for system, however what is recommended vs minimum configuration on their site?
Does one use the RIP for viewing files or use their workstation and remote in?
If using RIP what for previewing what graphics cards work best using linux?
RAM - 4, 8, 16, 32, 64 GB regular or Error Correcting at what point are there diminishing returns?
Hard Drive - I asume perhaps a regular drive for capacity but should one have SSD's for spooling or simply more RAM or RAM plus SSD plus hard drive?
Xeon or I7 or I7 Haswell with embedded video - or AMD?
1 or 2 network Gigabit connections to RIP - seems like 2 would be logical, 1 for to RIP and 1 for output?
Thanks,
Ken
