U Might Want To Consider An SSD Along With The HDD Since Its For Rendering And A 750W PSU Will Be Good, Allowing Future Addons And If Ur Willing To Pay Noctua NH-D14 CPU Cooler Is The Best Out There But Then Again Hyper 212 EVO Is Also Great, If U Dont Go Extreme OC. An Another 8 GB Stick Will Be Good But Dont Go For 2x4 GB Cause Well U Just Be Stressing Out Ur Motherboard Memory Modules In Case U Upgrade Ur Ram In Future And It Requires More CPU Power Reducing Performance A Bit
Other Than That Everything Is Fine
