Thanks for the reply, I can't seem to to find the exact specifications for the size of the hole on top of any kegerators. Do you know what the diameter of the hole on top of the series X is? If it is over 47mm I'm sure I can make it work!
Due to some plastic fins the hole is about 43mm but with that said you would fairly easily be able to drill out these plastic fins to increase the hole size to 47mm if required.
