I got a wireless adapter for my desktop computer thats PCIe x1. My computer was ordered barebones online so the case and motherboard are not the same make. I think the back slot on the back of my case does not line up well with my PCIe x1 connector on the motherboard. When I put the card in the bracket does not line up with the screw holes. If I push card bracket to fit in the holes it looks like it might bend it. How should I get it to fit?
