oil rig would be perfect, position it over one of the cold currents than make up the global "conveyor belt" heat transport system, and enjoy limitless water @3~

oil rig would be perfect, position it over one of the cold currents than make up the global "conveyor belt" heat transport system, and enjoy limitless water @3~4°c to cool any sized data cluster.....position it just right, and the rig can just tap into a natural gas resevoir and use that to power the data cluster, pumps, stuff, whatever, stick some giant wind turbines out there, paint them yellow, make everybody happy
