Just to follow up with my previous post, I went to HD, and measured all the side-by-sides they had sitting there (the associate gave me an odd look, haha). I found that the freezer sides were all about 12.5in wide when the size of the unit was 24-25 cu ft. The smaller ones, 21 cu ft and less were 9in wide or so.
I found a steal of a deal on craigslist... $20 for a 25 cu ft side by side, working of course! My buddy has the carboys, so I couldn't fit test the freezer with one. But the 6gal Ale Pale fits in just fine!
Anywho, bought 2 of the Fahrenheit aquarium temp controllers for $33 shipped! $53 total for this thing, can't beat that! They should be here next week some time.
Thanks for all the inspiration.
Cheers,
Lance
