The internal components leak comes from TVC-Mall. It shows a "dock connector charging port flex cable," which also houses the headphone jack for the device. There are also images that show a "replacement ringer speaker Dock connector module." Of course, neither of these images give any information that the average user might want, which would be in regards to the processor, GPU, RAM, storage, camera, and display.
TVC-Mall has posted component leaks from Apple devices in the past and has proven to be reliable, so despite the general boring nature of these leaks, they are likely real.
