We built a DUAL purpose RIP/Design
computer, We are doing a i7-3930K with 64GB of Ram. Its got (1) 240GB SSD for a system/program drive, (1) 120GB SSD for our ONYX Work Folder, (1) 120GB SSD for a Working File Drive, (4) 1TB Drives in Raid 10 for storage that is mirrored to a NAS.
We also have (3) PCoIP Zero Clients attached to this
computer for (2) for Design Terminals (4 Thread / 24GB Ram Limit each) and (1) for a RIP/Cutter Terminal.
This set up allows us to have a low cost of equipment and the ability to get more done. We might build a Dual Xeon system once we out grow this setup to allow for more Zero Clients / System Resources.
