It's literally waste heat, what else are you going to use it for? You won't efficiently generate electricity with it or anything like that. About the best you could hope for is warming up inhabited spaces in winter, but that ends up not being cost-effective because you'd rather have the data centers in the middle of nowhere where land is cheap (and you can't really transport the heat to where it's actually needed).
