Just completed blender rendering station. Mainly for cycles engine, on smaller scenes (<4GB) I render using both CPUs and GPU, which gives really good render times. When rendering more complex scenes I still can render pretty fast using 32 strong threads. 16GB of ram is for now enough, but I can expand up to 256GB in the future. Using Kubuntu, becouse linux works faster than Windows and in rendering evry second per frame matters, anyway Plasma 5 is bugged and I'm thinking about going to standard Ubuntu. May add dual boot Windows 10 in the future.
