Review on 27" Apple iMac All-in-One (Retina 5K, Mid 2017) MNE92RU/A, 5120x2880, Intel Core i5 3.4GHz, 8GB RAM, 1TB HDD, AMD Radeon Pro 570, MacOS, Silver by Mateusz Smoliski ᠌

Fantastic one-piece! The slow fusion drive is the only real issue with the base package. You should get a Samsung X5 external SSD connected through Thunderbolt 3 and utilize that as your primary boot disk. There will be an increase to 1700/2400 in read/write speeds. I also think you should up the RAM to 40 GB (+32 GB, two 16 GB bands). Various benefits, including a sizable screen, good color reproduction, a high resolution, and decent audio. The inability to replace the internal fusion drive with a ssd without voiding the warranty is a separate drawback. The case's monoblock ports are located on the rear.
