I promise to have better pictures soon and real drawings.
You are also correct that the refrigerator coils will need to be ventilated. That will be done through the back wall (top of sketch). Regardless of ventilation it will get warm under the counter, and the beer will need to travel through that space. I was thinking some sort of pvc channel that the lines sit in that is thermo wrapped with a fan in the kegerator to drive the air in a circle, has this been done?
At what ambient cabinet temperature would I need to start actively venting the hot air?
Also I just realized shanks are missing from my list. What do I look at here? Stainless? Bore? Short distance as I am putting them in the wall and thus going to use either plywood or a steel plate to mount and the length should be 3/4"? Do they need to be right angle bends?
Indeed, love the Emmett Brown quote.
I have seen some people use fans to cool a PVC tube. I've also seen some DIY glycol lines and pumps which seemed like a decent idea. Just search the forums for it, you're bound to find something that'll work for you.
I think if you just put a large enough vent on the wall, you probably won't need a fan to cool it. Personally I would put two vents, one at the bottom and one at the top to allow the hot air to exit from the top vent while the lower sucks the cool air in.
As for shanks, it's been a while since I've looked at them, but just measure the thickness of the wall and add an inch or more, it won't hurt to go longer on them unless you have some clearance issues on the back side.
You will need collars also to go around them also, and sometimes the collars will add a good deal of thickness as well depending on the type of collar you get. Right angle is entirely up to you. Either will work.
