Agree with the posts above. Especially about the planning ahead. I made one out of an old Rockstar energy drink fridge. I just wish I used a bigger fridge. It's nice that it has a glass door but only holds about 6 clutches. Last year it was great but this year I might have to make something bigger.
I also added a small fan into mine. You can buy some computer fans now that even have USB cables with wall adapters so they can be plugged into a power strip.
