I have a Genuine OEM Dell PowerEdge C6145 G34 Socket DDR3 AMD Server Motherboard 40N24. I was wondering what these pcie x 16 slots are for? I don’t know much about computers but it looks like I can’t find anywhere to install my gpu. It’s probably obvious. Excuse my lack of knowledge.https://share.icloud.com/photos/0ccNbGsfn5pwpAM0nF7W2r-vg
