We just installed our fuge last week. We drilled 2 holes in the side of a 10g container and put a bulkhead in each. We have one raised slightly higher than the other so that in the event that the one clogs the other will be a safety net. We also drilled a hole (that is supposed to have plumbers putty around it ... ahem... ) and put the return line back in through there. Cut a hole in the top and covered it with plexy to put the light hood over it.
