Was the 32GB of RAM a mistake? 
If not, save yourself the $80 as it is basically a waste 
😛
Other than that, one other recommendation, get rid of the Kingston SSD, and get a 500GB 850 Evo, that would be much better. 
Everything else seems reasonable.

This is not needed, you could keep the 250GB one, but you have more room on a fantastic drive
