Yes, at 22:42 on the 17th. I also amended my order to the 5950 CPU right after 2PM, however not sure how much that matters if they're prioritising orders that have been placed more than 30 days ago (not sure if it's all days or just working days) according to the T&C:
I don't know if they go by the order date or amend date if several orders are in this situation though.
5.2 Your order will be fulfilled as soon as possible after your Order Confirmation and in any event within 30 days of the date of the Order Confirmation, unless there are exceptional circumstances.
They go by the order date and its working days for the purposes of the T&Cs.
