I plan to use this computer solely for Lightroom. I have a Sony A7R so my raw files are 50-60 megs a pop so I need to know if dual core/high clock is better or if quad core/lower clock is better OR if pci-express trumps sata ssd. Please chime in.

Option 1: find 2012 mac mini i7 2.6 quad core, 16gig, apple SSD
Option 2: 2014 mac mini i7 3.0 dual core, 16 gig, apple SSD (PCI-E)

Caveats: I will pay the extra for apple SSD b/c I want trim and continue to update the OS.

Question 1: If the 2014 comes with a fusion drive, does that mean I don't need to buy the special bracket? I'm under the impression that a fusion drive is just software and inside there is a separate ssd + traditional drive so a fusion would already come with a ssd on the pci-e? So all I need to buy is the T6 security screwdriver.

Question 2: If I buy the 2014, which PCI-E drive would I need to buy?

so LR needs more processors than clock? and i'm guessing diminishing returns for SSD speed?
Both helps, but the iops difference between pcie and sata is not noticable and Lr utilizes all cores.

It needs to be said that unless you are batch processing massive amounts of files, nothing makes any relevant difference. Even the base mini with an hdd runs Lr perfectly fine. The ssd and cpu only make a difference, when importing and exporting.

I'm batch processing alot of files. the A7R raws are roughly 50-60 megs a piece and in batches of 100-200. The importing and exporting takes forever.

LR is definitely sensitive to clock speed but I can tell you from experience that the quad core is more significant and makes a huge difference. You did not mention generating 1:1 previews but those will be significantly faster, too.
