Making a build for a friend. His budget is $3000 and he will be using Vray. However, I'm not really too familiar with Vray so I mainly based it off of the puget system recommendations. What can I change to help knock down the price? I know I can drop the cpu for a cheaper threadripper, but not sure if that's the better idea or to get some other cheaper components (ex: cheaper gpu, cheaper case, etc).
