Hey JC I realize this post is old but if you give us the make and model of PC, I am sure we can find you a card that will fit it.
Also many boards have video ports that are strictly processor video vs onboard video and processor video can be flaky to
get going. Many video cards used to come with standard bracket as you are showing in picture and also low profile brackets
so again if we knew make and model of pc we could find you a card. Here is what the bracket looks like and you just change it:
