Thinking of replacing my obsolete iMac from 2013 with either a refurbished iMac Retina 5K 27-inch 3.6GHz Ten-core i9 (Mid 2020). It comes with 32 gb of Ram, 8 TB storage and seems like a very good deal for a little under $1,800. Or a new Mac Mini with 16 gb Ram, 2 TB storage for $1,700. I'd probably purchase a used 27 inch monitor for the Mini. I'd like to learn basic editing with iMovie and perhaps FCP, and have a lot of Hi8, BetaSP and VHS tapes that I hope to digitize and work with. Any advice would be appreciated!
