Earl,

any modern AMD or Intel CPU should be fine (i5, i7, Ryzen, etc) 16 GB ram minimum. get a mobo that can handle two wide GPU's just in case you want to expand your GPU rendering later. Buying an extra GPU will be cheaper way to upgrade later on than building another, faster machine. Make sure your PSU is 1000w or higher to handle GPU's and drives. Get a BIG case. I bought a mid tower case for my first build then realized later on it wasn't big enough for the extra card and had to buy another case for my second build.

W10, Ryzen 5 1600x, 16Gb,RTX2060Super+GTX980, PP11, 11.3.740
