I'm to the point of mounting the tower. How did you guys secure your tower? From what I have read, I purchased a piece of 1/2 plywood, but are you guys screwing the tower to the top/inside of your fridge?
I got lucky on my build. I used the four mounting holes as a template to cut a square hole through the foam. I was able to drill through the fridge and bolt the tower directly because it cleared the refrigerant lines perfectly. Since my square hole was so small I didn't need any plywood support on top of the foam.
