I have an old PC I want to sell, how much is it worth?

I have an old Lenovo ThinkCentre A62 in decent condition with a broken CD Drive.

Here are my questions:
- How much is it worth as is?
- How much is it worth if I replace the drive? (I have a spare)
- Will it sell for more as a whole unit or as parts?
- How much is it worth with the monitor and keyboard?

I know it's a lot to ask but I'm really unsure of what it's worth. I've looked online but couldn't find anything. Any help is appreciated.

Sounds like it's just an old junker, but I'm no pc expert… You can try to donate it, or sell it on ebay or craigslist, where other ones may be for sale

Maybe $15 with the broken drive, maybe $20 if you replace the drive, if you can find anyone to buy it t all.

An old broken computer, you'd be lucky to give it away. Everyone has an old computer in their house. Gosh, I've got 5 of them - one laptop & one desktop (that work). One laptop & two desktops that don't.

The hot things now are tablets & hand held devices.
