That is EXACTLY what I am looking to do.
I have been working @ss backwords with piecing my system together... Kinda sad really...
I bought my kegs before I bought a burner LOL. I found a great deal $30/ea keg and bought 4 three of which were matching brand shiner. so I have a set and a fourth to turn into a sanke fermenter for my 10gal batches.
I even bought my kegging equipment before I have brewed my first batch.. even got a 20lb bottle of Co2 filled at airgas $75 with a good hydro stamp, non rented just swapped a tank I bought.
I have this exact same freezer I got on sale for $129, and I have it full of food... but my SWMBO has already said I have to OK to upgrade... so I am going to get a 9CUft for food. and use the 5.4cuft for fermenting then add a collar and make it a keezer then add taps every other month as I fill up my kegs... which I have 6 of... 5gal corny's....
im telling you.... @ss backwords
