Build advice

[resiak]

So the computer is built for the most part. I'm running into an issue with the 4th gpu. The USB 2.0 header is at the bottom of the board as well as audio, well they are preventing me from plugging in the 4th gpu. 

I mean I could just do with out audio and USB 2.0, but I'd rather not. What do you think about using a riser? Is that an option?

Thanks again for your assistance!
