DIY Window AC Walk-in Cooler

[russ]

I want to build a modest 4x4x8' walk-in cooler. I'm wondering what others have done, what success you've had with the Inkbird controllers, and if there's a cheaper alternative to the Coolbot that hasn't been issued a cease and desist.

I'm interested in knowing which brands of AC units will work best, what BTU's of cooling are being used. Additionally, how is everyone keeping the humidity down for dry-aging meat?

I'm sure I will have more questions but this is what I've thought of so far.
