I purchased a new Hewlett Packard Solid State Drive and made a fresh install of the MacOS High Sierra.
The computer now comes with better configuration (8GB/512GB) than some new Apple offerings.
It will come with a bootable USB drive for computer maintenance or fresh OS install.
You need your own keyboard (or buy new one like MacAlly) and mouse.
If you don't have a monitor around, I can give you one, too.
Ideal Mac for a student or snowbird with a second home here.
This is the last Mini with an 8x slot-loading SuperDrive (DVD±R DL/DVD±RW/CD-RW)
