It has a very similar style to a Zone of the Ender's mech, but I don't think it actually is from ZOE. It doesn't look like it's from a Gundam series either, unless it's from the new one, which i'm not familiar with.
Nope, this guy was a final boss in Armored Core: Silent Line. Its name was IBIS, and it used a lot of directed-energy weapons. But I agree, it looks like an Orbital Frame.
