CeBIT 2005: SLI Shuttle Surfaces
Kez writes "You wouldn't think it could be done, but you can actually fit two high performance video cards into a Shuttle XPC and run them in SLI mode. Shuttle are being a bit coy about the whole affair, despite the fact that they have the system on show. As such, no internal photos are available, but HEXUS.net has a writeup explaining what's inside."

"unsupported" games may work but to try you have to make your own "application profile" if Nvidia has not released one. Basically all this involves is specifying which mode to use for specific programs.

I'm sure its pretty annoying for the average gamer though, to edit some obscure file every time they want to play a new unprofiled game. But then again Nvidia fanboys who are crazy enough to spend 1200$ on a pair of video cards will doubtless have no problem with this.
