Hmmm the next logical step would be a 'beer cooled system' - that might work
well if you were serving an English ale... have the beer sitting in a
fridge, hook it up and it should come out close to cellar temp.
Then again that could require a patient drinker if the flow rate is low, or
someone that would have to constantly drink the beer.
Either way, one of the better case mods I've seen!
