Okay, here is what I price your build out to be, approx. $840.
The big concern here for future proofing is the number of threads. Currently 4 threads is all that you need but that may change in the near future. For this reason I recommend looking at a Ryzen 5 1600 build. This will perform better in CPU intensive games requiring multi-thread performance. As well the 1600 can be overclocked while the plain 7600 cannot. Here is a BF1 video showing relative performance with a GTX 1060-6GB, notice that in general the 7600 is maxing out while the 1600 is in the 50-60% utilization. The Ryzen build also allows for faster RAM.

As far as onboard Wifi, the Pro4 does not have it. You have to either add a card or use a USB stick, I like cards as they have better antennas. But you can move a stick from computer to computer. This one allow for the antenna to be moved around for better reception and has bluetooth connectivity as well
