Looking at that Quad, and seeing your choice of SLI bridge... I think you should give it a go and make a custom one. I had a roll bar style cage like cover in my head to imitate the Quad bike frame. Some rods and a little soldering and I think you could do a sweet SLI job on that
Give it a beefy tough like presence yet stay low profile. Since the Asus bridge protrudes quite a lot.
i didn't even manage to get that far into the project before i encountered a serious issue with SLI.
Due to the chassis frame, the second card doesn't fit

Very lucky any card fitted, the top of the block (ports) barely fits between the chassis bars under the seat lol.
See here: how close the block is to the chassis

And here: The slant on the chassis bars blocks any use of a second card.

Everything is a little messy right now, working on it today, temporarilly pinning up cables etc while i figure out the best way to hide them.
