I got it, it was the last one and I can double confirm that it is Revision B. Thanked.
However now that I have it, I am likely going to go with the xkey haha.
I like the idea of playing the iso's straight off an external harddrive.
If anyone needs a Revision B drive (MSI DH-24AS). Let me know by PM.
I will let it go at cost.... otherwise I will just return it by next weekend.
