The 8600k is plenty for gaming, and if you want, with the H100i you can reach a pretty good Overclock.
The 16 gigs of RAM will be pretty good for a long time, and will give you the aesthetic look to draw in customers, once coupled with the S340 Black case.
The Evo drive has space for your OS, and select games with the 1 TB drive being for the rest. IF you doing a cloud service, then you can drop the 1 TB to save costs. Same for the OS if you have got a custom software.
The Z370E motherboard comes with Wifi to help keep all of your computers connected and in sync with each other, thus making it easier for you to control.
The main meat of the system is the Strix 1080Ti, which will ensure your systems will power thru all the games to come for many years. It is a beast of a card and will be perfect. It is going to pair well with your BenQ monitors.
If you need more storage you can set up a server or simply swap out the 1 TB for 2 or even 4 TB HDD.
