This is essentially my build, just a little more up to date with the processor. and is fully capable of running 'almost' all games on ultra in 1440p even most in 4k, but I like the 144hz g-sync monitor I have and it's so much cheaper to get in 1440p rather than 4k.

Cheapest or $1500? There is no cheapest $1500 system. All $1500 systems are $1500.
What currency? USD, CAD, NZD, AUD?
Do you need a monitor? If not, what monitor(s) will you be using with this system?
Do you need keyboard/mouse or any other peripherals?
Will you overclock?
Preferred aesthetic(colour scheme, side panel window, LEDs, etc)?
What will you use the system for other than gaming, if anything?

Your requests are still pretty confusing, but with that kind of budget and your requirements, I'd probably get something like this;

R5 1600 will handle gaming at 3440x1440 perfectly fine, and will be good for rendering videos. Stuck to the white/blue colour scheme as much as I could, with case, RAM, and even storage. Add some blue(or RGB) LEDs and you'll be good. A big chunk of the budget went towards monitor here, but that's because it's a killer monitor and you can afford it. Ultrawide, IPS, G-Sync, 100Hz. SLI support so you could easily add a 2nd GTX 1080 at any point if you wanted.
