Got mine as well - sounds like it's much the same as yours in that it's all there and the plastic looks new - there's just a little chew damage to the bars (hope that's not a prophecy of bar chewing
).
I knew fifteen quid was a rip off - I do a lot of ebaying and you can send up to 10kg via standard parcel for less than that - and there's no way and IMac's anywhere near 10kg.
