Title: [WTB] [WTT] Spondoolies SP30, SP31 and/or SP35 (or trade for NEW Antminer S5s)
Post by: eightcylinders on March 23, 2015, 07:03:11 PM
Looking for Spondoolies SP3x unit(s) including shipping to US (Chicago).  I will also pickup/meet if within a few hours of Chicago driving time.

BUYING USED SPONDOOLIES SP3x units (FWIW, I based prices off of pricing for used Bitmain S4's which are currently averaging ~ $0.27 / Ghs including shipping .. I rounded UP to the nearest 1/10th BTC versus the S4 pricing per Ghs to come up with the below prices).  Prices below include shipping to Chicago (or delivery if you are able to meet within a few hours of Chicago).

SP30 4.6 BTC
SP31 5.0 BTC
SP35 5.7 BTC

I also have the following to offer in TRADE, PREFERRED - all BRAND NEW in UNOPENED BOXES

FIVE Bitmain S5 <=> SP35
FOUR Bitmain S5 <=> SP31
THREE Bitmain S5 + .5 BTC <=> SP30

Bitmain's next S5 shipment is 1.293 BTC per S5, but mine are in hand ready to trade!  I only have 5 of the S5 units, so once traded they are gone.  In addition, I have 2 RARE water cooled Bitmain C1 each including the Bitmain cooling kit all new no longer offered and rarely found new batches sold by Bitmain at 1.123 BTC each ... in unopened boxes. If you would prefer to trade for the C1s or include the C1s in a deal, make me an offer.



EDIT: 2 S5's and one C1 can make a water cooled 3 Th/s S5 per below.  Very cool idea (pun intended).

They are not rare. Bitmain still sells them 275 USD +  C1 Liquid Cooling Kit X 1 50 USD + shipping

But they are still over-prized, and 0,85W/GHs

But you can get 2x C1 to build a water-cooled S5 and air cooled C1

Air cooled C1 is less as 0,8W/GHs

Still looking for sellers at the above rates.  I have been able to complete one sale, looking for more to fill out my rack.

Especially interested in trading the S5 or C1 units .. I will give a better deal to someone who can do that trade, as I cannot use the S5/C1's in my data center and they are sitting around doing nothing now.
