I might be moving out of the country in the coming months and am thinking of selling my late 2010 Mac Pro (3.33 GHz 6-core with Areca RAID) and downsizing to a MacBook Pro. Has anyone successfully sold a Mac Pro before and where did you sell it? It's a niche product and I doubt I could get any interest on Craigslist. Are such postings allowed here? Or is there another popular marketplace for selling mine?
