Best, going to be massive, and custom. Not sure who makes the most ridiculous cases now that Caselabs is gone. Try Lian Li.
If you want something more basic like a full tower, there are plenty out there that support 480mm radiators and the like. Cooler Master, be quiet!, Phanteks, all come to mind for full towers.
You've only listed two components, and to be honest, the chassis necessary to cool only that can even be a just a largish mid-tower. Basically just needs to support a wide motherboard.
Your selection is going to be driven by radiator sizes and component selection. Are you mounting any 2.5" or 3.5" drives? Adding GPUs to the cooling loop? Going with a large reservoir and pump?
