It's been a long time since I've updated...maybe seven years. I'm really liking the effort that has been invested into RGB lighting control. As an artist, color and motion turn me on. Anyway, below are some screenshots and thoughts. Kaby Lake is probably the last generation until what follows...which will be when?
 
The Case is the presentation. I'm thinking the Corsair 460X RGB case. Tempered glass and a decent mid-tower size works for me.
 

 
 
The MSI Z270 Gaming M7 board is colored well and has full RGB control. I really like that the VRM and I/O panel is covered and has RGB lighting, it gives the board a solid look.
 

 
 
The EVGA GTX 1070 FTW2 iCX fits my needs perfectly. I have also been looking at the MSI GTX 1070 Quicksilver OC. The photo below is the 1080 but shows the RGB LED layout.
 

 
 
I'm thinking Corsair Vengeance Blue LED (2 x 8Gb) 3200MHz. RGB memory is still coming along.
 

 
 
The hydro cooler is still up in the air. It will need to be RGB and there are three choices available: Corsair; EVGA; and NZXT. The screenshot below is with a Corsair in the 460X case.
 
 

 
 
I'll probably go with the i5-7600K.

The MSI mobo does look nice. I would need the ability to turn off all the lights. I'm surprised people would put the radiator in the front like that, but i guess with the large plastic I/O cover we see on Z270 motherboards,  it doesn't give you much choice, if you want to use a 280mm radiator.
 
I think NZXT has the best looking RGB.
(from your list)
1) NZXT
2) EVGA
3) Corsair
 
 
 

Besides the I/O cover maybe getting in the way of a radiator top mount the taller LED memory also gets in the way according to the Corsair forums. I also think the NZXT is the best looking.

Are you going to add RGB strips?

I haven't thought that far ahead yet. When this puppy comes together I'll get better ideas about that. I think I mentioned in another post that I will not be doing this build until late summer or fall. I'm hoping to pick up components along the way when they go on sale. I don't expect anything new from Intel for awhile, but another refresh of Pascal may come along by then.

i have corsair led ram and its shorter than the dominator ram but is taller than standard xms type ram (or crucial balistix tracer ram )

One thing I like to add about the NZXT is that the hoses block the first memory module.
Plus don't over do it with the rgb by adding led strips. The corsair crystal is a very visible case and you can't really hide the led strips in it to opt as a glow rather then looking like stop signs.
And the conflicts between corsair link and other rgb software is So Real. 3 out of 4 modules light up in my case. And sometimes none.
So the software is very faulty.
The rainbow colored G skill modules are too colorful, awesome but too fruity cough cough. I know they mentioned a software coming soon to control the colors and pattern but not certain yet.
I too am considering g skill ram.
I recently purchased mastercase maker 5t with the tinted tempered glass side panels and they dampen the light soo much that it looks sublime.
I was going to purchase corsair crystal 560 myself but the case not having a mid plate just made me say No.
Good luck with your build

UPDATE: August 2, 2017
 
I pulled the trigger and put something together. I'm happy with it. I went with different parts than I originally planned, but it comes close to what I wanted to do. The parts listed in my signature cost me less than $2,300 which was more than I was planning on, but it should provide me years of enjoyment and great performance hopefully for the next seven years...of course I'm sure a new GPU will come along.
 
The software that controls the RGB lighting leaves something to be desired. The CAM software that NZXT uses works great. G.Skill has a simple BETA version and it works pretty good, but sometimes I have to uninstall/reinstall the program to reset it. The MSI Gaming APP software is very limited with only about seven colors to choose from and needs to be restarted on occasion. EVGA's RGB control works somewhat, but needs to be improved.

Nice setup, looks good! Your cable management is on point.

I went the 460x route, and ended up getting the commander pro to control all the RGB lights for the case and fans. I have 6 of the 120HD fans and 4 RGB light strips all plugged in and can be individually controlled. I just wish the light on the Corsair pump/block could be controlled as well, it's a static light only but no limitation on color selection. Juggling software for RGB controls was something i was worried about so that's why I went all corsair since they had the link software for all their products.

Thanks_ Yeah, I went back and forth on which direction to go. I'm a big supporter of Corsair. I just thought circles would look good with straight lines. I think RGB lighting control will get even better in years to come.
 
And thanks for the other complements :)

It does look good, but you mentioned the one thing I had always questioned.  Software issues.
 
I cant even get my Corsair LINK software to work properly.  Probably doesn't help that I haven't bothered to update it in like... I cant remember.

Yeah, the software needs constant tweaking. The process needs one ring to rule them all!

Very nicely done! Do they sell RGB radiators and SSD's yet? It's about time....

looks nice.
