Power Supply and CPU Cooler suggestions

Hello Community,

I am new here and will be building my first NAS (unRAID) / PLEX server. I am having difficulty selecting a PSU and CPU Cooler, looking to be as power efficient and quiet as possible.

CPU: 2x Intel Xeon E5-2650v3
Motherboard: Supermicro X10DRi-T
Memory: 4x 16GB ECC DDR4 PC4-2133P
Case: Rosewill RSV-L4412U
SSD: Samsung 870 EVO 1TB
HDD: 4x Western Digital 14TB (shucked from WD easystore)
GPU: None for now, but might get something like an Nvidia P400 for PLEX transcoding

Will require room for expansion, one more SSD and four more HDD’s as required in the future

Thank you in advance for the suggestions
