Seems a pretty sweet deal considering it's a 3600mhz C16 and running latest award winning Micron E-Die, so should be able to run tighter timings or over clocked to 3866
Found a decent review for this here as it's still pretty new

Note: crucial says this ram isn't compatible with the tomahawk motherboard but users say it's works fine. Check website before buying.
Pretty sure this is revision E, no definitive info that I can find though apart from a supposed rep commenting on an Amazon Q&A. Also Buildzoid noted that it was a slightly custom PCB which is hopeful.
