i took a look, and if could jump in, i would suggest you take a look at this video :

this guys builds a great desktop pc for under 650 $. Just saying.
CPU : Great choice, have one myself and have had 0 problems so far (almost 1 year) and it comes with a CPU fan too
Motherboard : the only problem i can see is the price. Again, in the video above, he proposes an easy choice for the MOBO, the Gigabyte GA970 A, a great MOBO that has many onboard connections that can easily be accessed and an easy installation. Gigabyte specializes in this domain, so you dont have to worry about quality. Plus, it goes for as cheap as 50$ and has everything you need, including 6 back panel usb 2.0 and 2 back panel usb 3.0 (without the front panel ones) BTW
RAM, cant argue with that, Kingston, great reliability + you found a good price
Storage: search online, you can get the same for 30-35 $ ( try Seagate Barracuda )
Power Supply : I took a look at your components' specs individually, and you REALLY dont need 750 W, your not powering your whole house with this computer
Stick with 500W, its more than enough and only ends up costing 50 $ on amazon for a EVGA 500W (500B is more efficient).
Graphics card : good choice, OK price but cant really suggest anything else, only have had 2 GFX so far. ( newest one is 1 yr old )
LAST BUT NOT LEAST : windows, of course, i would go with windows
anyways, that's my advice, take it or not, its just a suggestion. If you have any other questions, send me a message, ill be around.
