Don't know about you guy's mini fridge, mine stands about 3 foot tall. i could probobly fit 4 2 foot monsters in there. but that's another story, and explanation.
I'd steer clear of the mini fridge setup's unless it's at least 1 and 1/2 feet tall, that's cutting it very close. Also, unless you can cut ventaltion holes in it, don't bother.
