external hard drive cases, what to do with them?

My office is throwing out the aluminum cases from hard drives. Does anyone have any cool ideas what I could do with them? Besides recycling. Thanks.

Finally got some pictures of the cases.
Use it as a power source for an arduino or an RPi.

You can sell them on ebay. Many people might use them for electronic projects.
