$2,500 · complete 5k Imac Setup

Selling a very powerful 5k 27" Imac with 2x 24" external monitors. 24GB RAM 2.12TB fusion SSD/HDD, 5k Retina, USB3, Video graphics, the whole setup. This Demo Unit Mac setup was part of my computer business that was 90% PC based. It has basically been a demo unit for clients for past few years. Now my work is almost 100% PC based so it has not been used or demo'ed in over a year. There may be 50 hours on it since I took it out of the box in 2017, though it is late 2015 model. everything is in great shape. its too much for me just sitting so offering it well below market value to someone who can make some use out of it. Fusion drive has had less than 100GB on or off it. Never upgraded from El Capitan though you certainly could. Will include the 24GB RAM upgrade in price and option to add 8 more to max its 32 gb capability for 100$ on top of the firm 2500 asking. Trades for?
