Me and my brother decided to work together and get an NES console (a broken one) and we want to build a gaming PC inside it. We have seen videos but most of them are just normal PCs and we want the PC to handle heavy games like COD, BF4, ext. We don't want extreme gaming but performance like at least 70 FPS or such but make the graphics look better that the new next-gen consoles such as XBOX ONE and PlayStation 4. But the most important thing to remember is that it all has to fit inside the NES. The dimensions of the NES are 10 inches long, 8 inches wide, and 3 inches. Please help out on this.
