What is this server being used for?
Intel or AMD?
No need for ECC RAM?
My Home Server has 32GB of ECC DDR4, With a Ryzen 2700x. I run ESXI and then Freenas in a VM with my RAID card in HBA mode passed through. Have 48TB of Raw HDD space (though of course real usable space isn't near that). Having ECC Memory is a must for such a setup, and so is a file system like ZFS. Allows me to run everything I want in a single box.
If you are going to be running something like unraid, it doesn't use a file system that protects from data rot. You need something like ZFS, as well as Memory that protects for errors. ECC is a must in a Storage system.
But if this is a game server, don't worry.
