Boom, mine now shows as paid. Thanks Bitmain! I wasn't kidding about that T-shirt doe 
Got 2.
I will assemble all my miners in them.
pics or cryptographic proof. Those are the only things I trust.

Regarding the PSU, I contacted Enermax to inquire about the ERV1000EWT-G. I asked:
(1) What is the expected MTBF for this PSU if placed under a 85% or 90% load continuously?
(2) What is the maximum recommended continuous load for this PSU?
This is the response I received:
Of course, the one caveat is that I do not know for sure that this is the exact model of PSU being used in the S2.

1. We do not have figures for MTBF at 85% or 90% load, but similar calculations show that at 100% load, the MTBF will be 42% less than in 70% load.
2. 1000W. Yet please note that the best efficiency of this power supply is at 350~600W load range. If system is constantly run at 800~1000W, we recommended to use 1500W PSU for best power consumption consideration.

42% of unknown is still unknown
Did they say what the MTBF is at 70%?
I couldn't give a rats ass about nanometers or "sexy" miners (seriously you guys need to get out more). All I care about is price, delivery, reliability, hash rate, and power usage.
Have to agree. "Sexy" looking miners that don't ROI aren't going to pay the bills. And women don't pull their clothes off because your server looks "cool". They pull their clothes off because your miner is filling your wallet with BTC.
Exactly. This guy is doing it right:

1. Exposed circuit boards and fans? Check.
2. Repurposed ATX power supplies? Check.
3. Miners that ship when ordered and ROI? Check.
4. Rat's nest of power and ethernet cables? Check
5. Girl taking off her clothes? Check.
All she needs now is an Antminer t-shirt.
How are the S2s coming BITMAIN? Any updated pictures for us? Some information on the number and fan types would be useful as well.

Does anyone still have any unresolved (paid immediately but expired) S2 orders made through the web site?
Not S2, but S1's yes.

That is normal for this seller.

Can't really base this on much, as apple to apple comparison shows that no doubt BITMAIN's S2 looks to be a great box, but I can't help the feeling that re-using the 55nm chip is a bit "old tech re-factored". While one S2 will generally be more effective than equivalent GH/s of S1 AntMiners, the S2 just feels a bit pricey at the current prices due to the chosen approach and position in the newly changed market (Spondoolies "ultra cool" form factor and Chinese A1 copycat manufacturers supposedly selling 1TH/s at $3000 now).
When comparing physical density 1.25U (Spondoolies) vs. 4U (BITMAIN) the newcomer takes a clear lead, but it will be interesting to see BITMAIN's 28nm setup as it becomes available.
I'd be surprised if BITMAIN wouldn't drop the S2 price to position themselves more favourably.

Mature tech isn't neccesarily bad. For instance they've managed to provide a lot more chips for the same money and so are able to run them at low voltages to achieve similar W/GH as the next gen, but with the benefit of lower costs, ramped up production capacity and consistency.
Seems like lower cost is a major winner - unless you're paying for hosting costs and rack "U" space. Running something at home - I'd rather see less expensive and less noisy. If the Bitmain unit takes up a few more U in my rack - and is quiet and I can't hear it all over the house - AND it's cheaper - then that will be a major deciding factor.

Well they both sold out first batches.. so I guess market is still pretty good for both offerings. Why would you drop the price if demand is good?
True that. Except a miner in May is not quite the same as one in March/April. But people will probably still buy they them since the are damn sexy.

Hey Bitmain, can you please check your PM or webmaster email. Have an issue with an order I placed last night and the payment being snail mailed soto speak (slowly making it's way to the BTC address).
The Israelis are going to give bitmain a run for their money:
