Selling it if it doesn't work should be okay as long as you indicate that in the listing.
Another suggestion for disposing of it--if you can't sell it--would be to contact your county or city solid waste department. If you're in a more metropolitan area, they may have the facilities to properly dispose of your old PC. If you're in a rural area, it's best to contact your county landfill to see if they have an annual drive for discarded technology (I know ours does). You may have to hold on to it for a bit, but you'll be able to feel better doing your bit for the environment.
Good luck!
