The cap has been leaking. when they explode properly they blow the can off. They blow up when the maximum working voltage has been exceeded.
As yours has leaked badly replace it but whilst it is off the board look for traces that will have been damaged by leaking electrolyte
The bridge is not gone because if the bridge rectifier on the PSU goes it pops the fuse at switch on.
Turns out something got toasted by the goo inside the capacitor, this was causing the restarting twice problem. I linked the two ends with a piece of aluminum foil and folded it down. The tin foil worked. Here is a pic:

That aerogel capacitor just goes bad by itself after a couple of years. You don't have to search for a reason why it suddenly starts smoking, leaking or exploding.
The xbox should work perfectly without it. The only issue you will have is that it doesn't keep it's time settings anymore if you remove the supply. It only keeps them for a couple of hours with the capacitor anyhow.
The smoking capacitor might have damaged some traces on your mobo. It is even possible that it damaged the power supply, and that one of the voltages is missing.
In regards to the capacitor, it has been removed, however it left the goo all over the motherboard and I have heard that this can be corrosive. Here are some pics:
Currently the xbox is working fine since linking the two ends with the tin foil. I only have two questions:
1. Is using aluminum foil a fire hazard, or a hazard to any other components?
2. Does the capacitor need to be replaced to maintain normal working operation of the xbox?
