Hi, I need a new mac for RAW editing. I'm mainly considering the following alternatives: 1) Wait for a Mac Mini upgrade (which may or may not take too long!), buy a high-end Mini, upgrade with SSD and RAM by myself. Buy a Eizo ColorEdge or a 27" Dell UltraSharp 2) The same, but buy a used Mini (latest generation). Same upgrades. Not very many of these around here in Norway, though. 3) Buy a used iMac 27", latest generation, with Fusion Drive. Put at least 16 GB RAM into it 4) Buy an older 27" iMac - but how old?? Put at least 16 GB RAM in it. If not Fusion Drive, I will buy external SSD's or some kind of RAID setup and connect via Thunderbolt or USB 3.0. I will boot from the external disks. I'm leaning towards 3) or 4), mainly because the Mini upgrade may take many months, and because the few new Minis on the aftermarket is often ridiculously priced. So my main question is really - how do I get the most of my money? I will use Aperture (or maybe LR in the future) for RAW editing, and I really want supersmooth editing with no lag. An SDD will be part of my setup, in one way or another. How old is too old when it comes to used iMacs? Is it better to buy an "old" one, because they are easier to upgrade by myself? Are the (used) latest generation really worth the price? Will I be better off with a Mini? Thanks in advance!
