So I have my eye on a used 2011 i5 21.5" Imac. I can get it for around $300 and will install a SSD in addition to the 500GB HD and probably max the RAM, so the computer will cost a total of $500-$600 when all is said and done. I was wondering if an old iMac was still worth getting if I max it out in this way? I plan on using the iMac strictly for art with programs like Photoshop, Illustrator and Corel Painter with my Wacom Cintiq. I also plan on using it to record and make music with, most likely with Ableton Live or Logic Pro. I have looked a some posts here in the forums and alot of people have been commenting that a 2011 machine wouldn't be worth it just based on the fact that it doesn't have USB 3.0 or Bluetooth 4.0 or the newer Thunderbolt connection. My question is, since I don't believe any of the audio interfaces I plan on getting or tools I own use USB 3.0 or Bluetooth or Thunderbolt 2.0, would the older iMac be worth getting? Would the SSD and RAM upgrades bring it up to speed? How good/bad is the 21.5" HD screen in comparison to other, newer models of the 21.5" screens? (Non-retinas, non-4Ks.) Is it good enough to see color accuracy for print? *I currently own a 2012 13" i5 Macbook Pro (upgraded with a SSD and 16GB RAM) that I use for art, deejaying, music recording and web-browsing. My new computer would become the main art/music machine with my Macbook Pro being used for web-browsing, deejaying and the occasional portable art session.
