Although I posted my Keezer already, I actually built my Kegerator a few months before it. Realized I never posted the pics. Here it is.
I started out with a Oster 5005 which has been displayed in this thread enough to not warrant pictures. I'll just show my modifications.
Took the top off and drilled the hole to accept the toilet flange (black abs pipe).
Then lined it up to finish drilling through the top insulation.
I then took 3" black abs pipe and 2 pieces of tubing of a larger diameter than the actual liquid line. I then filled the abs with spray insulation.
I then ran the liquid lines up through the sleeves and attached them to the taps.
I then fed the lines down into the Kegerator and pressure fit the pipe into the flange and put a cap on it. I sanded down the edge of the cap so it would blend better
