Inspiron 3847 GPU Upgrade

Hello! I am trying to install a XFX RX270 gpu into my inspiron 3847 but I am having some difficulty fitting it in the case. There are a couple cables on the motherboard that stick straight up that are blocking the card from sliding into place. I tried installing the card after removing the wires, and it does fit although it is pretty tight. I had to remove the ram to get it to fit. One of these cables goes to the disk drive (ODD2) and the other I believe goes to the power button (LEDH1). All I need to do is find a way around these wires. I was thinking of trying a PCIE extension cable or if possible finding a flat LEDH1 cable of possible. There is room inside the case for me to install the card elsewhere, I just need to figure out how to mount it. Any ideas? Thanks!
