You're right Ape, all capacitors will eventually fail at some time in their lives. The main reason I pointed this out is being that since this capacitor has a highfarad value, uses a lot of energy just for a clock circuit and is used very often it's most likely to fail way before any others do. And being that most people either don't care about the date and time or can reset it easily it's just better to remove that capacitor all together and not have to worry about it bursting in the near future.
What sucks is the corrosion from it can damage vital parts of the motherboard required for normal operation, so not only do we have to worry about hard drives and optical drives, we have to worry about that particular capacitor for the time being to keep the original Xbox running since its one of the first to most likely go out.
Of course sadly people that have a version 1.6 motherboard have to have that capacitor for normal operation, so they would have to monitor it more closely or get another version Xbox.
Now does that mean we don't have to worry about other caps on the board no, not at all. Those however should in theory last longer if we are lucky
Very true, sadly thou my Sega CD battery is still in tact but being it's 21 years old I should remove it soon.
