Alright .. no old PC thus no re-use.
Regarding WiFi: Nope, you'll need a PCIe version with brackets to support WiFi on motherboards.
That said ... considering your budget and everything that you need... would it perhaps not be an acceptable idea for you to go for 2nd hand parts/system?
This would allow you to get the same system performance for less money in general even if using slightly older components.
I mean the system in general will work but it is a mix-match of cheap stuff, but if you want new gear then for the budget you're in I'd recommend the following and it may be a little over but you'll be off better than what you had planned by far:
1. CPU:
AMD Ryzen 5 1500X Boxed Wraith Spire Cooler
2. Mainboard:
ASUS Prime B350-Plus
3. GFX:
Zotac GeForce GTX 1060 3GB AMP Core Edition
4. HDD:
WD Blue WD10EZEX, 1TB
5. SSD:
Crucial MX300 m.2 275GB
6. Case:
Corsair Carbide 200R Closed
7. Wifi adapter:
Gigabyte WB867D-I
8. Case fan:
Corsair Carbide 200R 120MM Fan
9. RAM:
Crucial Ballistix Sport LT BLS2C8G4D240FSB
10. PSU:
Corsair VS550
This brings up the overall quality of all components CONSIDERABLY whilst also maintaining a balance.
The Case Fan f.ex. is the case fan used in my linked case so you maintain an equilibrium with airflow for having the same fans.
You want your first build to be a pleasant one, not a cheap PITA one.
Edit:
In response to above post... you won't be using your motherboard for video output at all, only the graphics card's outputs.
The outputs on the motherboards are for the upcoming Ryzen APUs, not yet really released.
