That's a nice choice for a LAN rig, I don't really see anything that would hold you back for a couple of generations (current trend considered).

I would personally consider a CPU upgrade, to eek a few more years out of it, but that is up to you.

A liquid cooler should be fine... Pretty sure his case can support at least a 120mm AIO. As long as it is positioned as exhaust, the heat numbers should be fine at a modest OC

Just for the record though, you should check that your case can indeed support a 120mm radiator. Also, keep in mind how thick the radiator is other wise it might have clearance issues. Good luck with the build =)

If you're interested in VR, I would go with the HTC Vive. The motion controls are very good and games are easy to set up.

Well, nothing technically. But that minimum could change. It is usually a better idea to buy a CPU that is a little bit better than what you think you need, just in case. That way you will
 
a.) Get better performance
b.) Will be able to stay current longer
c.) Give your self a little bit of headroom

don't have pokemon go because of a lack of an android or ios device but, I'm just going to buy an amazon fire hd and a mobile hotspot and try downloading the apk so I can kill two birds with one stone..
