I'm selling my last Antminer S2. I have the original packing from Bitmain. It has the original stock 1,000 watt PSU in it. I've dusted it out, cleaned it up as much as I can. In the time I've had it, I've replaced the power board and two blades. It can be temperamental at times, particularly if it's pointed at a pool or coin that does a lot of rapid restarts (like west/nice hash or p2pool). That inevitably triggers some Xs that decrease the hash rate to as low as 970 GH/s. A power cycle always fixes the errors for a few days, then they come back again, usually running around 990 or 995 GH/s. If you point it at a "conventional" pool like Eligius or BTC Guild, it'll happily chug away at 1 TH/s for a few days before an X or two reappear.
I still have the two blades I pulled, Bitmain didn't seem to be interested in getting them back. They work, they just tend to throw Xs more regularly than the others. These are included in the package.
I'll ship it for $450 USD equiv to the continental US via non expedited shipping. We can negotiate on other shipping options if you want it faster.
I'm on the east coast of the US.
I'd prefer not ship internationally, as it's a pain and a hassle, but if you want to pay the extra shipping for it, I can probably work something out.
I'm also willing to just ship the internals to someone who needs them for spare parts. To clarify, you must buy all the blades and power board at minimum, I'm not going to sell off individual blades, as it's a fully functional miner that I'm using that is still profitable. If you get the blades and power board, everything else is up for grabs at your preference. The PSU is the only thing that will cost more on top of it.
Would prefer avoid escrow, as it's a hassle, but can go there if you insist. Note I've been around a long time and have plenty of good trust feedback. I've sold quite a bit of equipment here over the years..

EDIT: This is from one of the later batches of S2s. It has the reinforcement bars inside to keep the blades in place during shipping. Unlike many of the earlier batches, this one arrived to me from Bitmain in one piece.
EDIT #2: Fans are fully functional, nothing is broken.
