i replaced 5400 rpm hdd with Samsung SSD 840 Pro

I did it Rober's way - thanks - no disconnecting antenna in step 10

Stopping after step 12 and replacing hard drive there without removing logic board

I put the sheet that was around the old hard drive over the new one - not sure if its needed?

After it is all done i did Command + R to do internet recovery and get OS X mountain lion on the blank drive

Last thing to do is go here to enable trim: http://www.groths.org/?page_id=322
