I have a macMini as mediaserver at home.
To make it run fast with the new mountain lion i used the dual hard drive kit to install an sad hard drive as start volume. The original disk is additional for some space.
The 16 GB of RAM is to make it faster as well.
With the iFixit Guides it is absolutely now problem to safely install all the parts. GREAT
For all the Do It Yourself people.
This is absolutely GREAT stuff.
Thanks iFixit for the fast delivery even to germany.
