2012 Mac mini Fusion Drive or SSD

Hmm. Perhaps the best easy alternative would be to buy a 2.6 quad-core with a 256 SSD and 4 gigs of RAM, then expand RAM to 16 gigs with 3rd party memory, and add a new 1 TB USB 3.0 portable external hard drive to store files on. (I'd use an existing USB 3.03 .5" external drive for Time Machine backup and a couple of existing 500 gig 3.5" external drives for archival backup in the bank lockbox.) Any downside to that?
