Build your own walk-in cooler and do it on the cheap. This talk will outline how I built a 10’x4’x6′ space for approximately $150, via Craigslist and eBay. While it won’t be easy to repeat this cost, it can be done. Styrofoam makes up the majority of the supplies needed to copy this build. Best of all, it’s modular and can be moved without having to rebuild everything.
