So just bought this myself, seems a good price considering buying the CPU alone is £589 at Scan or £578 at OCUK, especially with the motherboard too making it roughly around retail price. Seems a good mobo with two M2 slots. the Wifi module is a bit of a bonus too.
No RAM or cooler just so you're aware.
Also went through TopCashback and got 2.66% there too bringing it to ~£613
