Dell MAR OPTIPLEX 7010 SFF i7 500GB PC

According to the specs here the memory type is DDR4, but on the Optiplex 7010 manual says DDR3. Is the model here correct?

I take it that the factory reconditioning is not done by Dell.

I am wondering the same thing.

No, looks like it’s by Joy systems. That said, it’s a compelling price vs Outlet.
