1) Kaby Lake runs off of Z270, not Z170. Z170 will supposedly support Kaby Lake with a BIOS update, but if you don't want the headache of wondering if the Z170 motherboard you've selected will run the CPU right out of the box, then pick up a Z270 board.
They did end up pointing that out, and I've switched to Z270.

2) If you can fit it nicely in your case, then I'd keep the H100i because more radiator space means lower RPMs on the fans, which ensures things stay nice and quiet. Ever since I moved into the water-cooling sector last year I've been putting together custom loops that were more than the bare minimum so that I can keep my fan speeds lower while.
Cool deal. The case I picked fits it.
I haven't learned much about fan speeds and temperatures yet, do you know any good sources of info you'd suggest I check out?

3) SATA SSD vs NVMe M.2 SSD
Will read, thanks : )
4) If you're going to stick to a SATA SSD, are you going to be throwing both your OS and games onto the same drive? I probably wouldn't do that unless it was a Samsung 850 Pro, since the EVO uses a cheaper type of NAND which is going to wear out sooner than the Pro. Or... pick up a second SSD and separate the games from the OS because that's probably a lot of reading and writing to just one SSD with TLC NAND.
One of my friends originally suggested going with separate drives for this reason, and the other one talked him into saying 1 is just fine because that's all he ever does and doesn't have probblems.
Lol, love these style debates.
If only one EVO is being used how long of a life expectancy could/should be expected?

5) Do you need W10 Pro? The Pro version doesn't do what it used to, and the Home version has almost everything the Pro version has, especially for someone who just simply uses a computer on a daily basis and doesn't have any special needs. So, if you need Pro, then get Pro, but if you don't and you can find Home cheaper, then I'd say get Home.
That was old info not getting edited out, my bad. Never had intention to get Pro, just home. And on USB not DVD since I probably won't get an optical until I have a good reason and I guess USB is transferable once if needed. Also my buddy that's going to physically put it together told me to get USB so, he's the boss lol.


Thanks for the response.

Assuming I don't mind using video settings that are just good enough to not die to fire.. how many accounts do you think this build could run?
