Hardware recommodation needed

Hello,

Since i was told my old xeon 5440 is too old i am looking for a New Server.

I was told i3 would be fine.
Its only for freenas with NFS and cifs shares in 4x 1.5 TB + 1x 3tb disks with zfs
The four disks in z2 .

I need it for sharing Fotos and Videos. Recording onto the large disk from several TV receivers.
But after all not much traffic at all or not many users.

I will buy 16 GB ECC RAM of course.

But the Problem is the board and cpu.

Would be a socket 1156 board be OK?
Or should...
