First of all how big is "giant"? and second... how are you planning on cooling a "giant" tank down to lagering temp?
Most commercial ferm tanks of any real size are stainless steel and jacketed with are then electronically cooled with an automated glycol pump.
If you're not going to go with a fully jacketed tank, you would need to cool the tank itself down to lagering temps and again... depending on what you mean by "giant" will dictate how you're going to have to pull that off.
