PC build advice

[Sabroo]

Hi everyone,
I need your help. I'd like to build a PC.
Specs:
CPU: Intel Core i7 4790k
GPU: MSI GeForce GTX 960 4gb
MB: MSI Z97-GAMING 5 ATX LGA1150
What are you recommendations about RAM, HDD, PSU and cooling? Or about changing components written above? Thanks for your help
