iPhone 6 Motherboard broken at the top, will it still work?

Hey!

Maybe this is a silly question, but i bought an iPhone 6 of of Ebay for $15 and it has nothing but the logic board, battery and screen in it. The thing is, a piece of the motherboard has broken off at the top. As far as i know that piece only contains the connections to the power and volume buttons flex cable and the WiFi antenna. I dont know if there is something else crucial up there.

My question is, will the Logic board still work (apart from the WiFi and Side buttons of course)? I cant test it myself since i have no parts on hand. Hopefully someone can answer this question :D
