Trying to replace my Mid 2007 20 inch iMac. Looking to spend $1000 or so and have it narrowed down to these two models which seem almost exactly identical. any ideas on which to get? Late 2013 for $999 https://www.amazon.com/dp/B01I0F6BTA/ Late 2015 for $1099 http://www.ebay.com/itm/Apple-21-5-iMac-8GB-RAM-1TB-Late-2015-MK442LL-A-/201750898582?rmvSB=true Leaning towards the 2013 for price. I'm not worried about the 1TB 5400 spinner, ill deal with it or replace it with an SSD in the future.
