I own the late 2015 27" iMac version of this computer with the i7 chip, 256GB SSD and the AMD Radeon R9 M395X GPU. I figure it should sell privately for less than $400-500. This one, for sale on Amazon, has a Fusion Drive and an i5 chip so it's worth even less. Another thing to keep in mind with this computer is that it is only going to get Security Updates from Apple for about another year and a half.
