I just spoke to OcUK on the phone and had my order split so mobo is on its own order. The lowdown is that there is no ETA on mobo deliveries for any model. It could be 2 days, it could be 2 weeks. Bummer!
I even phoned around locally and everyone is in the same boat. The only Z690 in stock was a low-rent looking MSI Z690-A which I'm not interested in lol.
OcUK will now ship my CPU, AIO and other bits today arriving tomorrow and I'll just be hanging around for the mobo.
I may actually end up changing the mobo from the Asus pre-order to the Gigabyte since we're in this position.
Snap, just did exactly the same on the forum support section. CPU arriving tomorrow, Mobo (Maximus Hero Z690) backordered. I think it's important to keep the orders together, to easily qualify for the £100 asus cashback offer.
Hopefully ASUS prioritize OCUK for motherboards, since they likely have hundreds ordered. Hope it's nothing like the Asus Strix 3080 scenario
