I have heard many people to wonder about, what are the differences between the two 2009 models of the Mac Mini – early 2009 and late 2009. So here I will show the differences about this two models and even with their predecessor the 2007 Mac Mini – you may wonder why I am writing this, but again some people are wondering if there is a meaning to get a second hand 2007 Mac Mini or to go with the newest one.

Conclusion
This are the differences between the different models of Mac Mini, as you can see even the 2007 models is very capable machine if you want to use it for something different from main computer, such as web server, home theater or backup computer. But if you want to experience the full power of this tiny computer get yourself one of the late 2009 models, mainly because of their powerful processor.
