Custom build PC for 3D rendering only

Hello,

I am trying to do research on building a PC just for 3D rendering. I model in Sketchup and render in Maxwell plug in. According to the Maxwell requirements, I do not need anything special in terms of graphics card. My budget is $1500-$2000 and would like to use New Egg.

Here is what I have gathered so far. Please let me know if any of these are not compatible or if there is anything better or more up to date for similar price.

Thank you!
