UPDATED: The situation resolved itself when the controller card started acting flakey. This was probably a result of me trying to jam that second card and the riser cable into the mb at the same time. Eventually, I released the magical blue smoke from one of the leads on the riser cable. The bay still seemed to work, but it seems probable that I damaged it, and the card itself is still fine.
I have an Asus II Rampage Gene (in a 4U rackmount case). It's got a RAID card on the 1x slot, and a "double wide" EVGA 660 GPU on the x16 slot farthest from the CPU.
The RAID controller leaves no room for a second GPU.
Here's what I'm considering, in order of most preferential as I perceive it:
Obviously, I could ditch the RAID card and solve this problem, but I'd rather not for a few reasons, not least of which is that solving this sort of problem is half the fun.
I'm assuming that latency is not an issue for either card if I add 12-30cm of cable to the PCI bus, but I could be wrong about that. I'm worried that the extra millisecond introduced by the riser cable on one of the GPUs could turn out to be a problem down the road in an SLI setup.
I assume this isn't an original problem, but I can't seem to put the right words into the Google machine to find a solid answer.
Any help is appreciated in advance.

Here's what I'm considering, in order of most preferential as I perceive it:
- Daisey chain two 1x riser cables together and run them up between the GPUs in order to "extract" the controller card from it's current bay.
- Move one of the GPUs and the RAID controller down a notch with a 16x and 1x riser cable, and hope that I can find an aftermarket SLI bridge long enough to reach.
- Lose the RAID controller.
