Looking at upgrading my 2014 iMac to a 2017 iMac. Have the intention of maxing it out with everything. 64GB ram I will do myself, already have 64GB from OWC (bought here in Australia). The 2TB SSD has a premium price here in Australia +$2,240AU. I have 1.3TB of data on my fusion drive now, I want to avoid having external drives hanging off the new one. I will also take advantage of the 18 months interest free offer for purchase but paying it all off before the expiry of the interest free period. Have many others here gone the 2TB SSD option, going through the threads here it doesn't seem so.
