I want to build a truenas server with the cheapest CPU I can find that can support ECC RAM: Celeron G4900T + 64gb ECC RAM + 4x18 TB SAS drives.

I don’t have experience with ZFS or with truenas (core or scale), how much important is the CPU?

Use case: hundreds of thousands of small files mostly under 1 mb, but just 2-3 concurrent users

    CPU is not that important for ZFS itself, but it’s important for network communication. If you plan to saturate 1G connection or faster with your storage, you will need a CPU with solid single-threaded performance, or a discreet “smart NIC” aka DPU, but that’s really for way bigger speeds.
    If you plan to use a couple of spinning rust drives with no ssd cache, you are fine with any reasonably modern CPU (like Core/Xeon ~2012 and newer, Atom ~2016 and newer).
