You can run the airline from your Co2 through the drain hole above the compressor on the Sanyo 4912, this is what I have done. You will need to remove the rubber grommet for the drain hole first though. The 4912 will hold Two 5 gallon cornies, if you want to hold more then get a bigger fridge and do a custom setup--you can always search http://richmond.craigslist.org/
to find an older fridge to convert.
