Couldn't resist any longer and just ordered a new 2014 2.8ghz/8gb/1tb fusion Mini on sale at B&H Photo for $529. Have been using a base 2014 1.4ghz/4gb/500gb HD mini as an iTunes server for the past 3 years and have been concerned about what I might replace it with when it inevitably dies (it runs 24/7 in a closed cabinet). The new mini is too expensive, and frankly it's over-powered for what I need. So this seems like a good deal (Apple sells the same model as a refurb for $849!). My thought is to split the 128gb SSD from the fusion drive and use it as a boot drive (just like a 2018 mini, LOL), then use the 1tb internal HD as a shared network drive. All my media is on an external 3tb disk that is cloned to a backup disk every night. 128gb is more than enough room for the boot drive, I think the old server only has about 50gb on the internal drive. I found this guide to splitting a fusion disk: https://www.lifewire.com/split-fusion-drive-apart-2260166 What are your thoughts? Is there a better guide somewhere? Is there some reason why I shouldn't do this? Apparently these Mini's ship with Sierra pre-installed. That is fine with me, I'm also running Sierra on my 2012 quad Mini and 2013 MacBook Air. But is there some reason why I should update to a newer version of MacOS? This machine just runs iTunes with home sharing and file sharing enabled. Don't use it to browse the web, send e-mail or anything else. The old 2014 Mini is running El Capitan and has been very stable, it only gets re-booted two or three times a year.
