Seems fine to me, but I question the need for such an expensive CPU cooler and a soundcard when your motherboard has a dedicated audio chipset.
Liquid CPU coolers use more fans, which really just equates to more noise, combined with the already very low power consumption of the 7700k. Personally, I wouldn't shell out money for it, especially since their failure rate is higher (and they're harder to fix/replace). As far as the sound card goes, I'll admit I know pretty much nothing about sound processing, but from what I've gleamed, sound cards really don't make a difference anymore since most motherboards (such as yours) come with onboard audio chipsets.
Also, the motherboard you're buying has onboard wifi, you definitely don't need a wifi adapter.
