On the odd/fat chance that someone out there has configured a BTO Mac Pro with an SSD, what kind of bracket/adapter does Apple use? The IcyDock I had been using in my old MP is giving me problems in the 2012 Hex (I keep having to reseat it). Can these things be bought separately from Apple? I've searched the online store and there is nothing listed. BTW, I already have another SSD in the ODD bay.
