Hey mate, seems you are from UK.
BTW why are you buying stuff from laptopsdirect.co.uk??
There are many number of sites to get cheap parts, like this site :
https://uk.pcpartpicker.com/ (this website checks the compatibility too)
sites like alza.co.uk, ariapc, novatech etc (haven't double checked the prices at laptopdirect.co.uk, but they never came for cheap when I was building my RIG).
BTW I've build my RIG with ASUS Z210P, accommodated 8x1060 cards on it (including 2xM.2 as well), haven't had much issues so far, been running from past 8 months (using nvOC - Ubuntu though).
