I try not to bug this community very often but I really need some advice. I purchased it Mid 2011 and this past summer the Applecare expired. Just recently the LCD started acting up and two lines have formed across the screen. I took it to the Apple store today and was told it would cost around $500 to replace the LCD. Even the genius agreed that it wasn't worth paying that price since its almost half of a new iMac. I've invested quite a bit of money into my mac including adding 16GBs of RAM and installing a 128GB SSD. Should I sell it on Craigslist? How much would I get for it with the bad LCD? Here are the specs for my iMac: 21'' 2.7 GHz i5, 16 GB RAM, 1TB HDD, 128GB SSD.
