Luke,
I have only used it once and it was 95 degrees outside. I had the kegs iced and the beer poured extremely cold. I was having some issues with foaming. I would get about one second of foam as soon as the tap was opened then it would pour great for about 8 ounces or so, then back to foam. I tried both lowering and increasing the CO2 pressure anywhere from 8 to 25 psi with the same results. I haven't exactly pinned down what my problem was. Aside from the foam it worked great. I will continue to trouble shoot. If anyone has any suggestions / theories please let me know.
Here are some more pics of my setup.
Underneath the cold plate I am using a wire silverware tray that I trimmed to fit inside the cooler, similar to this.

I wish I would have thought about how I was going to run the tubing out of the back a little more, but I suppose it works.
The last picture also shows my DIY tap handles. They are a bit large for the jockey box but are right at home on my kegerator.
