Chest Freezer Fermenter Size??

[boombrewer]

I'm looking for a chest freezer to make into a fermentation chamber. I can't figure out what size to really look for though. I'm thinking at least 9 cu. ft. so I can put two carboys in there at once. But I know you lose so much to the compressor hump.

Has anyone ever tried building a collar (like many have done for a keezer) to give the height needed to put a carboy (6 gal) on top of the hump?

Also, anyone ever try building a small (single carboy size) foam chamber to enable running two temperatures inside the same freezer?

Just some ideas I've been kicking around. Thanks!

ferment in kegs and you can fit more in no matter what size you get

Thank you! I don't know how I missed this but I definitely wasted a couple hours.

An 8 cu ft fridge of rectangular top open design... you should be able to get 2x 5-8gal buckets/carboys/Spiedels side by side or 4 ball lock cornies. I just went through the research and purchase.... but that chart is the tits
