I have a base model 2012 mini that I upgraded the ram to 16gb and added a samsung 840 ssd as a second drive. Its working very well. I bought osx server to do some file sharing and post some websites for my web development classes. Plus it was only $20. My concern is that I have my mini set to never sleep so that I can access my stuff whenever I need. Is it okay to have it set this way? I also use it as my home desktop. I was kicking around the idea of getting another mini and using one as a home server and the other as my desktop. Thanks!
