You can build a NAS that supports ECC, but two conditions must be met: the CPU must support ECC, and the motherboard must support ECC. Just because a CPU can work with ECC-type memory doesn’t mean the platform will actually run it in ECC mode — the board’s chipset and firmware must explicitly enable it.
For Intel, real ECC support on off-the-shelf components usually means using either a server/workstation motherboard with a chipset like W680 or a true Xeon platform. With W680 boards you can pair certain Intel CPUs and get ECC working properly. Consumer motherboards with other chipsets generally do not enable ECC even if the processor technically supports it. 
For AMD, many Ryzen CPUs can work with ECC memory, but whether ECC actually functions depends on the specific board — some AMD boards advertise that they support ECC, and in practice a few builds successfully detect and use ECC; but others simply run the RAM without true ECC error correction enabled.
Here’s what that means for your plans:
If ECC is a priority (for TrueNAS ZFS data integrity):
You want a combination where both CPU and motherboard specifically support ECC. That usually points toward either an Intel workstation/server board with a compatible CPU, or a board/chipset that explicitly advertises ECC support with a CPU that also supports it.
If ECC is not strictly required (many home NAS users tolerate standard RAM):
You can use a strong non-ECC setup with things like modern Ryzen or Core CPUs on standard boards and still run TrueNAS or similar software. It won’t have full ECC protection, but it will still function reliably for media streaming, file storage and even lighter VM/Docker workloads.
