Hi all, I'm looking at getting a mac. Originally I was looking at a Mac mini however, the prices they are commanding for the 2012 version is silly (£350-400 ish) so I started looking at iMacs. I would love it get a 5k iMac with a 2tb fusion but cannot justify 2k on a computer. I have seen a second hand 2013 model,3.2 i5/8gb/1tb for sale for £600. Two things than concern me. The 1tb spinner being really slow - how difficult is it to upgrade these? And is buying old tech false economy in the long run? Would I just be better off buying the newer one and sucking up the £1400 difference? Advice/ answers appreciated.
