I just wanted to turn my computer into a incredibly powerful machine for gaming, I wanted to know if I can put two mother boarads in one computer. Having two GPUs, two CPUs and all of those components that go on the motherboard double. Are there any power supplies that can do that or any cases, is it even possible? If it is I also wanted to know if I really need to buy a huge and expensive case, just put the motherboard on some other smaller case.
