This is sooo tempting.
may want this. this is not the s7ln correct?
This is 135 chip Antminer S7, so batch 8 or later S7 (nominal hashrate 4.73Th/s).Are you going to fire up this with the Enermax PSU from the group buy we had if you deside to buy this Phil ?
See my setup with the 1000W Enermax for reference:

I used 1x 16AWG PCI-E splitter to have a total of 6x PCI-E for hashboards and 1x PCI-E for the controller.
Everything is divided evenly between 3pcs. 12V rails, so the overload protection would not be a problem
(they are separate rails only in sense of overload protection).
Sorry OP for bashing in to this thread, but I thought maybe this would be useful info
NO prob whatsoever. Essentially, correct.

no, this is originally late batches S7 miner, which sidehack converted to low power using PIC.
see reference in first post where he describes it.
Let me know.

For sale: Bitmain's antminer S7 (135 chip), voltage adjusted (PIC-adjusted) by sidehack.
Original description is here (miner #61):
https://bitcointalksearch.org/topic/fs-undervolted-s7s-37-4th-870-1050w-024jgh-with-psus-1556664
3.7Th ONLY 870W, for 0.234J/GH, making it a very low power S7.
It will remain profitable for much longer than regular S7.
running at around 3.7th requires boards running hot at above 55C (best achieved in environment of 70F and above, 80ies are fine), so you can play with reducing fans to achieve that.
Price: $270 before shipping to US only (should be about $15-18).
