I have a 2006 CD Mini, 1.83GHz, with a dead drive. I plan to use it some more, as a homework/surfing/email machine for the kids, probably internet games, too. Should I just throw in a cheap HDD or go with an SSD? OWC has a 100GB HDD for under $40, that's almost scandalous. Even a 30GB SSD is nearly twice that. My media is all served from another computer, so I'd put basically nothing but apps on here. It would be wired Gb ethernet. Maybe 30GB is enough and the speed would be more useful day to day? Looking for opinions.
