I bought the 2013 Mac Pro in my signature as the base Quad model for £400 earlier in the year, and upgraded it with the better CPU and 64GB OWC Kit. Just been quoted around £900 by one of the mac buyback retailers, so that'll see me in profit by about 30%. I could sell it on eBay et al, but just looking at the dates of the last of those to sell I just see them as complete fantasy. So i'll just be selling to the buyback place and getting a mini to go with the MBA, because the mini with 16GB RAM, 512GB Storage is less than £1000 through work.
