I posted a "wanted: broken/old mini-fridge" on craigslist, and got a really nice one for free!

Now what?? I saved one link on converting them into incubators, but the instructions are a little confusing... does anyone have a SIMPLE plan for doing this, preferably one that doesn't require removing freon & fancy tools? Here are some photos of the fridge - how many clutches do you think I'll be able to put in here? And what size flexwatt strip/s should I get?





Do I have to remove all of this?
