It was a bit of a rushed decision.
Everything is mostly fine, except for the wireless adapter.
The adapter is a Realtek RTL8188EE. ( https://wikidevi.com/wiki/Realtek_RTL8188EE_Reference_Design)
It only has one antenna connector.
I checked through WikiDevi to see if I could find anything similar by Atheros or Intel, but every time I get to a site like newegg or Amazon and take a look at the pictures, it always seems they have two antenna connectors.
