Hi, I am able to get my hands on a 2011 iMac 27in i5 3.1ghz for £1000. It has 32gb ram installed and is in good condition. Comes with keyboard and mouse. 1tb 7200rpm hard drive. I really want an iMac for Lightroom as my trusty 2010 unibody MacBook over heats when using it. I can't afford a brand new one. What do you guys think? Is it worth it?
