The fact that the label has a red 'X'-ish logo instead of an Apple makes me think the label is maybe NOT an Apple-original. (Unless someone else can confirm having seen ones with this logo.) Maybe a reseller upgraded it and made their own label?

There is likely to still be an Apple logo on the machine in the normal place for a 5xxx, just under the screen. Can you confirm this steve30?

I do recognize that purple and orange logo as well but I'm not sure where I've seen it before. I've got quite alot of old Apple educational documentation so it's probably in amongst that somewhere.
