Thank you very much Wacko. I kinda want to pull the trigger today but your opinion helps me I make up my mind : Will build my own rigs and keep all the boxes for to flip them later on in case these coins tank.

Coming back from a long time lurking. Rig B I would want a really good deal to consider as difference between 1070 and 1070 ti is not a whole lot, and the new TI is more efficient with right settings.
I think you are going in right track in building your own rigs. I would just decide what coin you are trying to mine as I see AMD and GTX as each having advantages and disadvantages.
