Looks good and almost zero modifications to that make it about as simple as can get! Thanks for sharing, it gave me some ideas on how to make mine if I go that route (I'm debating between a cooler similar to yours and a mini fridge) and after watching that I'm liking the cooler idea more and more for its simplicity.
Lmao @ "it actually works really well up there... despite how short i am."
I really like this method. I was planning on using a cooler too but i wouldnt have thought to flip it on its side. The only thing i may do differently is drill holes and run the fans wires out of the incubator right next to where they are just so theres not extra wires hanging around in it. I like it a lot though, gave me the idea of flipping the cooler on its side.
