Title: Massive amount of S4 watercooled on eBay
Post by: adaseb on March 03, 2016, 08:48:35 PM
Was browsing eBay and found this
http://www.ebay.com/itm/161995889295


Seems like a pretty impressive mod job with the water cooling and the initial bid of $1000 is a steal pretty much. I guess if you are local you can pick these up cheap.

These are great miners.

That guy posted in the S4 support thread about those miners. Seems a massive undertaking to watercool that many of them then say in the description that they are "junk". Could well be worth a bit of experimentation if he were to split them. But it looks like hes trying to sell the whole lot.

If I had am airconditioned datacentre I would by the new ones from him. Its a shame im just a home miner with a couple of S3's  :D

S4s may have once been great miners but you need electricity at under 8 cents per kWh just to earn enough to power them up.  Their efficiency is only 0.7 J/Watt.

After taking into account freight and purchase price you would need electricity under 5 cents per kWh to even consider this purchase.

I don't believe a lot of it.  They say " We have Bitmain Antminer miners 220pcs new in box."  For a S4 to still be new in box at this point and 220 of them for this amount of time seems like a very unlikely thing.

The water cooling job I don't think was to great they say "This also comes with 150pcs S4 miners already converted with water cooling with water blocks, but many of them don't work well so please treat them as junk."   That tells me you will recieve them in parts... and treat as junk 150 unit's that is a issue.

Someone is trying to get out of the game with previous gen gear.... but I think they waited to late with shipping costs.  And considering it sounds like the water cooled ones are considered junk to them.

Probably they just bought the boxes from Hashnest :)

Maybe when he says 220 pieces he just means boards, If i remember correctly the S4 had 4 boards in each box.

220 pieces is only 55 complete boxes...

I read it as 220 units.  If it waas meaning boards I think he would have had to put hashing boards (and would be a weird way to sell by board number).

That being said I cant imagine anyone paying much for these as a group.  I think they would have done better selling 1 at a time.... but looks like they are in a hurry.

It's possible that the units are "new" given the loose definition of "new" for Bitcoin and Bitmain. If they haven't had a previous owner, they might have been sold as "new" even if they had been hashing for months. That of course won't really mean anything in terms of their condition or warranty.
