DIY Aquarium Chiller made with a mini fridge.

I'm trying to get the water in my aquarium colder and I've been looking at some chillers but they're so expensive. I found some YouTube videos about how to make a chiller with a mini fridge so I want to see if anyone has had any success with that before I jump into a project or to see if I should just bite the bullet and buy a chiller.

Have you looked at other options besides those two? Perhaps closing the room shades and adding a small room A/C unit? Relocating the aquarium to another, cooler location? Evaporative cooling if you only need a few degrees of cooling works too. Perhaps keeping heat tolerant fish?
