Homemade cabinet/mini fridge incubator question

[Aiden Kendall]

I've found a mini fridge that I'd like to convert into an incubator. However, due to the shape(indentation at bottom where compressor was) of the inside of the fridge,
I don't think I could put a false back in it to circulate the air as the store bought models do.

My question is this: Is the false back an absolute necessity?

If you've built or seen one without the false back I'd love to hear from you. And if you haven't but have an idea, your input would be greatly appreciated
as well.

Thanks in advance.

A pipe with a fan in it running up the corner would work. You just need a way to pull hot air from the top an it come out on the bottom.
