I have a small Sanyo fridge, too short for std. kegs. Had same idea, but, too likely to rupture lines, and, coolant may suffocate you. Will try to sell or trade on craigslist. There's more: In this state, and undoubtedly the entire country, before trash collection, you are required to have coolant collected by a tech. This cost me $30 ten years ago. The tech tapes a form to the drained unit, as proof.
So, what do you think will happen when you show up with an illegally-drained unit? One big, fat $$fine$$, probably.
