Which wifi card (m.2 or PCI-E) for Gigabyte H370-HD motherboard build?

[zuzuzuzu]

We have ordered a new hackintosh. I wondered what is the best way to implement wifi nowadays. I have built a few macintosh so far.

The power of the card does not have to be very strong, the router is like 5 meters away...

What is the best OTB solution and alternatively what is the cheapest?

Thank you!
