Well, if you don't have access to thermite or even a large sledgehammer then this recommendation of his might be a cost-effective solution:

Even if you do have that sledgehammer this might be useful as a preprocessing step before final treatment with the aforementioned hammer.

I'm fortunate in already having some of the tools in this kit and some experience in their use and I can highly recommend this technique, not only for data destruction but also for relaxation and a source of various unique parts.

I wonder how many of those clocks made from HD platters contain sensitive information; definitely something else to worry about...
