Or rather, read the model number of the motherboard you’re ordering carefully – and make sure you click on the right “buy” button.
So I got an Asus P5WD2-E Premium, when I really wanted an Asus P5WDH Deluxe. Idiot. Which means, not only do I have to pay £9 to send the incorrect board back, but I have to pay delivery charges on the replacement (order value <250). And, the DH Deluxe is £20 more expensive!
