Yes, we do have that law here too, I could send it back to Kustompcs and they've already said that they'd happily refund me.
I don't know what the correct part is - the LE may fit, it might not.
It looks like it _could_ be exactly the same, just with this bit removed.
It's not going to cost me anything to get that part removed though, and it'll be quicker, cheaper and easier than sending it back
Besides, Kustompcs don't stock the LE version yet, so I'd have to wait until their next order from AC.
