I don't know if I've been the only one looking around for a D0 stepping 920, but I found this on e-bay and bought one. The seller has confirmed the model # and s-spec. It's priced lower than newegg. I think it's a hot deal. If you can't get to a Micro Center this is the way to go.

Without D0 I'm pretty sure
I think there were 9 available so check it out.
