Well I finally had time to finish this baby up. I even got to christen it properly with a poker game that went through a keg and a half.
I decided to bolt down the tower, I wasn't happy with the stability of it, especially with one of my large aluminum tap handles on it. I drilled 4 holes for carriage bolts, the tops of the bolts are sealed to the fridge insulation with silicone. On the inside of the fridge I put some metal tape over the nuts.
I also decided on a way to cool the lines in the tower without actually requiring a fan or anything. I cut 2 lengths of copper pipe to extend an inch into the fridge and to within 1" of the bottom of the goose-neck on the shanks. I then sprayfoamed the void in the tower.
The copper seems to be working exactly as I'd hoped in that it is transmitting the cool temperature of the fridge up it's length and keeping the lines cool all the way to the shanks. When I pour that first beer it is the exact temp as the water in the fridge that my thermometer is in.
Here's a close-up of the assembly in the top of the tower.
And here is the finished kegerator. The tower isn't actually crooked, it's just the picture. I even used a level to make sure it was perfect!
