Topic: WTS - 300 CoinTerras anyone? 600,000 watts of fun! (Read 1411 times)

What is the nm specs of the current mining ASICs? Last miner I have sold was a 28 nm machine...

going to be in that area later in the month , what are you looking for per unit?

Well there you go. What were they, about $3 apiece for that length?

I have a good setup for crimping pins right now, but not for the ring terminals so a huge batch of those cables would still take some time. Unless I bought or built a better crimp setup for ring terminals, which could happen especially if a couple thousand cables were desired. That would knock the price down as well.

Okey. I try to find 380x 4Gb card so had to ask

asus 7950 or 7970

What card was in one picture top of pile on motherboard? "A stack of them:" picture...

I have access to free shipping within the 48 states. If you are going to recycle them can I have them?

Personally, I think the PSUs are the most valuable.  They already have breakout boards, and are pretty close to what is needed for mining.  New, they are something like $375 each (at least that is what Digi-Key: http://www.digikey.com/product-detail/en/bel-power-solutions/PFE1100-12-054NA/179-2421-ND/2627912 and Mouser are selling them for: http://www.mouser.com/ProductDetail/Bel-Power-Solutions/PFE1100-12-054NA/?qs=He7j%252b7NElcPW2NXHzvQBUg%3D%3D).  So, that is something like about $750 new per CoinTerra for the PSUs alone (the price new, not used, but the PSUs are in great shape and come with breakout boards).  The liquid cooling could be valuable, fans are worth a few bucks, the BeagleBone is worth a few bucks.  The hash boards are probably junk (I don't think there is anything to get off of them, but I could easily be wrong - SIDEHACK - you are the expert here).  The case is all aluminum, maybe worth something.  I was actually wondering if I took everything out, if I could put some GPU rigs in the case.  It looks like everything would fit, there are already PSUs and fans for the case.  The cases might be a good way to rack mount GPU rigs.

They would easily fit in a 20' shipping container.  That would probably run about $3000 or so from SF to Europe (last I checked a year or so ago) and would take about 1 month.

Anyways, there are some good options, but I really don't have the time to deal with it, I wish I did.  Parting them out, I figure there might be $50,000 ~ $100,000 worth of equipment there, but I just might end up recycling them if I don't get any interest here.  It is a bigger project than I can handle right now.

Sidehack, that is an excellent plan.  If there was say 6 PCI-E cables per PSU, what would 3,600 PCI-E cables cost with ring terminals?  I don't know the best config, but maybe something like 3 PCI-E cables attach to 1 ring terminal, so something like 2 ring terminals per + and -?

It could be as simple as getting some 2~4 AWG ring terminals and just soldering in a bunch of PCI-E wires to the ring terminals.  Then you have a > 1 kW server PSU that is platinum and runs great at 120 volt.  That alone would be pretty cool (+ a bunch of other goodies like the BeagleBone Black, Delta fans, liquid cooling, etc)!

Hey Klondike, just the man I want to speak with!

I think they are compatible with Intel boards.  The company that looks to have made the coolers (http://www.coolitsystems.com/) looks like they specialize in Intel systems.  I scanned over their info and it looks like coolers are designed for Intel Xeon CPUs.  I am not 100% sure about that (I have not physically tied this), but this is what it looks like.  If it was really important to someone, I could physically verify this.


There are 2 of these per radiator:



A here are the 2 radiators:



KLONDIKE - You are the man when it comes to cables, what do you think about making some cables to attach to the 4 AWG wires?  I am sure I am not the only person with a CoinTerra that isn't running!

Oh, I almost forgot.  These machines are super clean, they were run in a very, very clean environment.  You can see from the pictures that everything inside the case looks almost new.  I didn't clean anything for those pictures, that is what the inside of all of them look like.

Wow these were very prized Bitcoin miners not too long ago. These CoinTerra units are made of 28 nm technology?

Shipping one with UPS/FedEx would cost about $50 each, so not really worth it.  I think it is really only worth it if someone just grabs a truck and gets all of them.  You could probably get a truck for about $1,000 and drive them about 1000 miles and back (about $2000 to get from the east cost -> west coast -> east cost).  That would make the transportation cost about $3 ~ $6 or so each and would make it much more cost effective.

I forget who for offhand, but I've made cables with ring terminals that mount right up to the breakout board on these PSUs. It's not very hard to reuse them.

If anyone is willing to go 50/50 or less on this to Europe I'm interested, surely there's something to be done with the watercooling, fans and PSU, IMO just the hashboards and maybe the heatsinks are to trash...

I know it's a long shot, and customs + 20% VAT will kill all hope of profit (oh yeah, and a continent and ocean to cross, right) but if anyone's interested I'd love to work something out or even examine feasibility !

Cheers,
Q.

PS : thanks for the pics OP

anyone know if the coolers can be re-used in a desktop? I assume they lack the correct sized bracket for intel boards?

Sent you a PM as you see may pay a bit MORE to get ONE unit to see what real shipping is to me and to try and play with the PSU etc (and hell just to run it for a day
for its lovely bitcoin space heating properties) and for your trouble ....likely shipping will be so frigging high I'd not want anymore..but we can see.....


anyway sent you a PM...likely I can't mod the PSU's but could use some cases for projects etc

what the heck .....if shipping does not suck too bad and I can mod a psu or two for SOMETHING I may get a few more....likely much less then the demo unit price I
sent you above for your time on this ..iffy.....proposition...for the ONE I asked for to look at in the PM.

anyway good luck on your project

what the heck things to look at make wirrly noises..then take apart and trash for other uses

I always wondered about those psus, I didn't know it was exclusive from these miners..

What's the efficiency, 1W/GH? I have free power, but I'm thousands of km away. And we will need a lot of cable, space, and a whole ship LOL

Good luck with your sale man.

You must be a millionaire to be able to buy 300 of those at $10,000 each. Wonder if you ever ROI'd.

Thanks for the pics.

For shits and giggles:

Unfortunately, I don't have any that provide a good perspective on them, but here is a few...

Here is when I had to throw them in a U-Haul, just to move them a few blocks:







A stack of them:





Another view of that same stack, from the side:






I wish I had better images, they are just crammed together with a bunch of junk thrown on top.  However, you get the idea...
