Based on published photos, the seperate audio card has to go somewhere between PCIe x16 slots 1 and 4, i.e. the two most seperated PCIe slots where your two
gtx260 cards will be if you go SLI. But that places the audio card exactly where the rigid SLI bridge needs to be making it impossible to seat the bridge on the SLI card edge connectors. So apparently, you can have your choice of SLI, or, audio but not both. I don't see any other place for mounting the audio card. Is there a way to resolve this so you can have both audio and SLI?
