I am thinking about building a large Unraid server in the near future. My goal is to fit as many hard drives as I can in a case - preferably hot swap but not necessary, use an old motherboard/CPU, and various old sitting on the shelf gathering dust hardware for the core build.
This system will be mostly a storage server - MIGHT run KODI or Plex but not necessarily.
What I know I need:
Case - obviously
MB/CPU - I have an old Ryzen board with a 3 or 4-series processor on it.
RAM - 16 or 32 gb of RAM sitting on the shelf
video card - I think I have a 1080 or 1070 sitting on the shelf but won't matter with unRAID
Controller - LSI 16e or something like that from ebay, cable adapter for SAS to SATA.
USB drive - unRAID runs off USB if memory serves.
Hard drives - ServerPartDeals is going to LOVE me.
M.2 SSD or something for cache
Is there anything I am not thinking of? I will be coming from a Synology DS1819+ w/ DX517 that is populated with drives in 2x SHR-1 arrays. Would setting up let's say 12x 20TB drives with 2 parity drives be something reasonable to do?
