My employer has decided to block external hard drives on our laptop so I am in the market for a new computer (my first mac!) for my photography hobby. I don't do any gaming or very heavy duty stuff. I need to run Lightroom and the Nik Collection (I use the latter as a smart filter in Photoshop even though I don't use PS as such, so no layers etc). At decent speed, that's all I need. So far I used a laptop with windows7 64bit, i7 1.7ghz quad, 8GB RAM and 128 SSD so I would like the new mac to be approximately as fast. Questions: 1) Is the standard configuration of the mid range Mac Mini good enough for that? 2) Do I need more RAM? I am happy with how those programs run with the 8GB on my laptop but of course it is a different OS and system. 3) Do I need the SSD (or Fusion)? The pictures (c. 500GB) are all on an external hard drive, will the SSD make any difference in the editing or I will just get a faster boot time? Will LR be faster? 4) If i go for the standard config can I add a pcie ssd later? And RAM? I live in the UK and prices are 25%+ more expensive vs US (mac mini mid is £569/$900 here) so adding options gets expensive ($250 for either SSD or RAM), would like to get only what I need. Thanks!
