Re: Inspiron 3470 SMALL desktop
It has a PCI-e x16 slot on the motherboard which should take a video card. But as Mary G said, you will need a low profile (half-height) or a small form factor graphics card.
Not recommending any specific card or seller, but check these for their dimensions to see what size will fit inside your PC.
