I had a 2009 IMAC which still works fine, but really wanted a new late 2015 27" IMAC which was supposed to be refurbished (which is fine). I received the IMAC in a new box that included all new components including screen tape over the 5000K monitor which indicates to me it is brand new. The IMAC works as advertised and the 5K Monitor is superb and has the clearest sharpest picture I have ever seen, much better than the 2009 IMAC. The IMAC starts up in less than 60 seconds and is blazing fast with the 2TB fusion drive with SSD. I purchased an extra 16 GB of DDC Ram and installed for about $90 bucks on Amazon for 24 GB of Ram. It is everything I wanted and would definitely advise anyone interested to purchase.The only con is the price but they do work forever if my 2009 IMAC is an indication..
