For some bizarre reason, all of Intel's Haswell i3 chips support ECC. 
They'd actually probably make pretty good CPUs to put in a ZFS box. Apart 
from only being dual-core, the i3-4340 (
is no slouch. 3.6 GHz Haswell ain't half bad.

Some of their embedded chips support ECC too, but most of them are meant 
for soldering and not sockets. The only one left of note is probably 
the i5-4570TE... it's a bunch slower than most i3 chips, so the only real 
advantage that it's a 35W TDP part that supports turbo (with a max turbo 
speed of 3.3).

Regards, Adam.
