What to do with an iMac G3

I have an old slot-loading iMac G3 laying around acting as a playpen for dust bunnies. It's a great machine with an iconic form factor, phenomenal speakers and great build quality. The big question is, what can and should I do with it? Is it possible to gut it out and fix in a Mac mini or other small computer into it as well as an LCD? Or is there any other hack or use for one? Thanks in advance! Also, how long does it take for a CRT to discharge completely if it ever does?
