Old PCs and PC accessories - Do you Dispose and How?

[_Cathy_]

I have a hard time disposing anything that still works - like my PC that I bought in 2004. I don't remember the specs anymore, only that it's an AMD Duron. It works most of the time



I need to clear up some space and I don't know what to do with my old PC. I want to know if I can still sell my PC. However, I cannot dispose of my PC yet until I can transfer my back up files using my old PC:



How do you dispose of Old PCs? Do you give it away? Sell it by parts or as a whole? Sell as junk?
