If your focus is on V-Ray Next CPU, and you want very fast rendering without a huge price tag, this single CPU tower is a perfect fit. It uses AMD's high core count Threadripper processors, which offer a lot of CPU cores for excellent performance with V-Ray Next CPU - as well housing up to three GPUs to boost V-Ray Next GPU. With version 3.6 and higher, V-Ray Next GPU can also utilize your CPU alongside the GPUs, so if you go that direction the many cores on this platform won't be wasted.
The combination of high core count and good per-core performance in AMD's Threadripper 3rd Gen processors means that this system is great for 3D modeling and animation as well. It is more expensive than a pure modeling system would need to be, but will handle your work in applications like SOLIDWORKS, 3ds Max, Maya, and Cinema 4D very nicely even before you are ready to render.
