So help me out here...  basically all I would have to do is take the cards out of the case - plug the extender cables in where the cards were before - plug the cards into the other end of the cable, and separate them on a contraption outside the case somewhere?

Is that right?  Would everything else work like it is right now when I plug it all back in?

Thanks

Since I have to buy 3, can you tell me how much a cable should cost so I don't get ripped off?  (I assume I can leave 1 video card in the case and just separate the other 3) ?
