After tax+shipping for where I am it came out to $121. This is quite a steal for what this is. I suspect it hasn't been hit much because of the fact that it doesn't actually say 9405W-16E.
As far as I can tell the only thing NetApp about it is the sticker over the back ports; no custom firmware it seems. I was able to download firmware and storcli from broadcom here (hopefully that search link works correctly). I did it in efi with storcli.efi to flash the firmware and bios files no problem; not even really a "cross"-flash.
I'm *pretty* sure that any bracket for any of the 16E lsi/broadcom cards will fit this one. I just ordered one that said it was for the 9206-16E, but I haven't gotten it yet to actually say for sure it fits so be wary.
Only 7 left attow, sorry
