Looks like I was the only one left out of the loop on this one then. No worries, I just wanted to make sure that your offer was taken seriously, because you seem like an honest user just out to buy some hardware. You actually don't even need to know the email to make an attempt at recovery. I don't want to clutter up their thread here, but take a read through this thread -

"Typically, the only acceptable method of proving ownership is by signing a message (including current date and desired new email address) using a Bitcoin address or PGP key associated with the account. A Bitcoin address or PGP key is associated with the account only if the account posted the key/address, sent it in a PM, or if it is still listed in the account's profile." - Theymos
You can make a post in Meta to better understand the process or shoot me a PM and I'll do my best to answer any questions.
I'd be very interested to hear how this deal ends, by the way. Once you receive the package, let us know that it is in working condition and that the hashrate is as expected, etc. Happy to see that this ended up in someone's hands that knows what to do with it, are you going to be able to pull a profit with this thing?
