6th Gen (2015) 4GB HDD Not great in 2018.
can;t find on itzoo at the moment but better price and value with 256gb ssd, so yea, not a good deal. https://www.tech-bazaar.com/product/dell-optiplex-3050-sff-desktop-pc-intel-i5-6500-3-2ghz-8gb-ram-256gb-ssd-win-10/
pretty poor if you ask me, expensive for what it is.
Poor deal tbh, itzoo had similar setup with ssd for just over 200 still under dell warranty (refurb)
