If you had to choose, cost is the same! Previous Generation 2,3ghz i7 Quad Core Mac Mini Server, with a 256gb SSD plus a 1TB Hard Drive. 16gb RAM Or Latest Gen 2,8ghz i5 Dual-Core Mac Mini with a 1TB Fusion. Which I would swap out the HDD with a 960GB SSD thus creating a Fusion PCIe/SSD set-up. 8GB Ram. Cost wise are the same, so just a throw up between the two..... I use the machine for Media storage, YouTube and general spreadsheets. Machine isn't being taxed. I can't upgrade the RAM in the later gen Mini, but 8gb should be fine really?
