MP Select Mini Micro SD to SD Adapter Holder

This will put an SD to micro SD adapter in an easy to access location while allowing the side panel to be removed so that the adapter can easily be unplugged in case you have to remove the bottom plate.

This does require that the two piece version of the 60mm side cooling fan be used.

The Micro SD TO SD Card Extension Cable Adapter can be found on Amazon.com
I wasn't able to find the same one I ordered but this one should work as well as any other.
