Q: what should i do with a centris 650

Hi afelkner,

I am not sure quite what you are asking, so I am going to presume for the moment that you are wanting to dispose of the computer, which is over 20 years old.

Apple offers a recycling program that you may want to take advantage of. You can see the details on this page -

Thanks for using Apple Support Communities.

Best,
