Well, you can put your machine in a closet and never turn it on, ever :)

I don't know if this was mentioned already but it is probably useful.

Hello security gurus, this one's for you:
After shutdown, is it possible to recover the data stored on the
Random Access Memory? Be it an ancient mounted ramdisk, a tmpfs mount
point or normal data kept in memory by programs.
