i am also building the 8ft kegger bar and have used both the pink insulation and the shiny aluminium insualtion. i used the shinie insulation for the inside of the keg box in case i wanted to incorporate a light inside – the walls will reflect light. i am still in the progress of constructing the fridge but i plan to use alumium tape over all the seams. I am really concerned that this might not keep the items cold enough but i am willing to give it a shot. No on to you keg supports you can realy make them how ever you like, you just want to make sure you will be able to put a keg in the box. I want to incorparte a fan (1 or 2) of them in the box but am not sure how to give them power. Any suggestions??
