Can anyone please confirm if non-Apple SSD will work in the $1819 refurbished Mac Pro currently sold on the Apple website? It's the 2.8GHz Quad-Core Intel Xeon MC560LL/A. I was on the phone with Crucial earlier and they said their SSDs would not work in that machine, which I thought was odd. I've read lots of posts on thie forum about cloning the OS/apps/etc over to an SSD, but is there something odd about what is currently being sold by Apple?
