Standup/Upright keezer build idea

I'm kicking around the idea of using a 21 cu ft stand up freezer for a stacked full size keg keezer build. Basically, one full sized keg on the bottom and one on a shelf at the top with the lines going thru the door in the front. I've already made a single full size keg keezer for my house but this 2 keg design will be for a club bar. I'm going 100% function on this one not anything too fancy. My first concern is the shelf holding nearly 200 lbs and withstanding a keg swap once or twice a week.

Anyone had any experience with full sized keg keezers or something along these lines? Any other ideas I should kick around?

This guy used a 20 cu ft upright freezer for his corney keg keezer.

I'm not sure how the weight of six fully corneys measures up against the weight of a half barrel, but I'm sure you can do the math.

Do you transfer your brew into half barrels? Or is this for commercial brew?

It's for commercial brew for right now. I'm not sure how home brew will go over quite yet.

That build is exactly what I had in mind except with 2 fulls instead of cornys. Even the price is inline with what I had estimated (adjusted for a 2 keg system). Thank you for the help!

Did your build work out for the two commercial kegs?
