Thanks and I found another plastic rack system at home depot. Its $50 and it has 5 shelves. Heres the link to the video on how to set it up https://www.youtube.com/watch?v=DLDxk2yp2Vs and these racks that this kid builds in the link hold 18, 28qt tubs and itll cost around $150 to make.
Those snake racks will work, as I had a friend build one like that. Just remember that the room they are in will need to get no colder than 75 degrees. I also recommend using foam board to cover 3 sides of it, if you decide to go that way.
