Hi there, I am wanting to start a hardware design project and found an AGP riser extension cable (http://goo.gl/UE3op) that is perfect for what I need, however I have a couple of questions; 1 - Will the increased distance between the Graphics Card and the AGP port cause any noticeable performance changes? 2 - Is it possible to get the same type of cable for RAM and PCI slots? If not, can you get custom made items like that? Thanks!
