I got this mobo:
https://www.newegg.com/Product/Product.aspx?Item=N82E16813128868

As you can see, it has:
x1 PCIEx4
x1 PCIEx16
x2PCI

I should plug my GPU (GTX1070) in the PCIEx16 slot, but I have a wireless network adapter ( https://www.newegg.com/Product/Product.aspx?Item=N82E16833704059 ), where should I plug it? I know the silver plate must be aiming to the outside of the case, but (I think) the only way to make this happen is to plug it in the PCI slot, even though the label says PCI-Express.
Sorry for bad english and thank you in advance, I hope you understood what I just wrote.
