Can you provide the specs on the drives (manufacturer and model number or other details)?

These servers will hold 4 3.5 spinning harddrives, they are just not hot-swap but they can be removed, upgraded whatever you want to do. Limited in size only by the os that you use. Server 2016 Essentials would work great on this with (say) 4 12tb drives. This server has plenty of memory as will.
