good gaming PC build?

[MrHayden73]

im wondering if my current specs for my build are good, or if i should change things. so far, my list is as follows:

cpu: i7-4790k

motherboard: asus z97 maximum vii hero

gpu: asus gtx 780 6gb strix

case: corsair carbide series air 50 ATX case (black)

HDD: 500gb 7200 rpm hdd

SSD: 512gb

cooling: corsair h50 liquid cooling

ram: 16gb G.skill ripjaws 1600

power supply: not sure, somewhere around 700w though

anything missing from this build? anything i chould change? im quite new to building pc's. and i do have someone to build it for me, just so you all know.

Get a larger HDD, Custom liquid loop, or drop liquid cooling. Don't need 16 GB RAM or i7 unless rendering.

Get PSU tier 1, 2 or 2b here https://community.newegg.com/eggxpert/computer_hardware/f/135081/p/45344/323055.aspx#323055
