We had a very long day yesterday getting all of our hardware moved into our private cage.  We were able to roll 3 of the cabinets into the cage, but we had to move everything by hand for the 1st cab.  Also we got Group Buy #4's monster GPU rig all installed as well.  Here's some photos of how everything turned out.

We had the corsair 1200's on hand; we've been looking at server power supplies and having some custom cables made up to provide a ton of pci-e plugs. I found some on taobao done up like that and they are very cost effective.

Here's our 7 card 290x monster rig from Ninja Group Buy #4.  It's a rack mounted tray design meant for deployment into a data center cabinet.

With a box fan sitting on top of the cards they stay around 75C, pulling 930kh/s each.  They are scheduled to be installed into our rack later this week, and we'll sort out their airflow/cooling situation then.  This one is going on the bottom rack of one of our cabinets; with 2 airtiles popped right in front of it.  If I were to do a full cabinet worth I would go with max 6 per 4/5U case, enclose them and pressurize the case with high CFM server fans.  This is all highly experimental of course (and fun!). I'll post an update later this week after they move to their permanent home.

So I know most of this hardware will never pay for itself at this point (but that's ok) and my electric bill is going to go up until my 7.2Kw solar panels get installed. The video cards will eventually be switched to litecoin, but for now its all running BTC.

Rig is 2xMSI HD7950 Twin Frozer
        3770K i7
        16GB Ram
        Array of 6 Cairnsmore CM1's   

Air cooled with a $15 honeywell fan placed into a hole cut with a rotozip.

BFL on order since Feb, so this will have to suffice until July when that shows up. Sucks how high the difficulty has already gone up.

This is nearly all sold out, there are maybe 5 spots left total.

Buyback completed here: https://blockchain.info/tx/fd0cd829af14ccb7c0f778c3fff42894f8db481a6cb6cd2b7a6677337a548e8f

Happy to ship you (or your ebay buyer) hardware, just refund the buyback and pay the shipping. We haven't seen hardly any demand trying to sell them off, best offer I have gotten so far is $500 per unit. Maybe you'll have better luck.

Agreed.  I'll post shipping label instructions later today.  These unit will ship out on Wednesday (we're headed to inside bitcoins for the first part of next week).

Options are going to be as follows:

1. Owners with Multiples of 4 shares -  Send a shipping label and take the hardware. Details on dimensions/weights to be posted later today. The $99 NOC fee is waived for those that prepaid hosting.
2. Buyback at market rate of the hardware less $99 NOC fees (will be waived for those that pre-paid hosting).  Currently around .2/BTC per share, but will be calculated Wednesday when the buyback completes.

A final payout will go out Wednesday and the machines will be pulled offline at that time. 

Upgrade kits for our S1's have arrived; now waiting on a large order of thermal grease.  I'm expecting that we will have them upgraded on Monday.

No time to work on the stats page at the moment, busy building out a new warehouse and upgrading 100 S1s.  I've been testing Nicehash/Westhash and the results look good, once the upgrades are done I will move the miners there and anyone can get the stats based on our payout addr.

We have upgrade kits on the way.  We have a warehouse space rented.  We're on the cheapest utility in Arizona and headed into winter rates. We have a unique heat containment cooling solution that works great for these small warehouse mines.  We have room on the power panel for 120 Antminers total - Well be running 4 -  3 phase 60 amp circuits, and we'll be pulling just under 200amps continuous power once cooling is factored in.  Broadband to be provided by Cox, with a 3G backup dongle on the router. Security by ADT, plus cameras, and multiple levels of locks.

We're building the mining room starting today. I'm on my way to home depot to get materials. We're offering the remaining capacity of this operation to members of Bitcointalk as a group buy. There are exactly 120 spots, of which 80 will be sold here (40 pre-sold before the offering). Your miner will go live as soon as our upgrade kits arrive and we get them done and installed, orders will be processed in the order received. As with anything we offer now, you have full control of the mining hardware via our innovative Mining as a Service (MaaS) interface.  We don't touch your earnings ever as you choose the pools.

Each Group buy member shall receive:
1 Mining Space for 1 AntMiner S3 or Miner of Equivalent form factor/power consumption.
1 Antminer S3 (upgraded S1 to S3+ using kit)
1 500W Lepa Power Supply rental (or similar, may use other supplies for owners with multiple miners).

Monthly Fees: $45 (.095btc) per miner/per month, with a 6-month initial term, month to month after that.  First month and last month included in the upfront payment. Send us a shipping label anytime after that and we'll send back your miner. Simple. Cheap. Reliable.
The mining space is reusabe, so you could also switch to an L1 in December. 2nd Month payment will be due 30 days after mining commences.

Miner Cost: .525 BTC
Hosting (First and Last month): .19BTC
Total:  .715BTC

Payments go here and nowhere else: 1NiNJAGi1k51pfxKsQQQisf3MMwsPU5yCc I won't contact you via PM unless you initiate the conversation thread, and will always quote our conversation.  Anyone messaging you otherwise is a scammer. Make sure you control the address you pay from of course so we can always verify who we are dealing with for your own protection.

You still get paid when someone else in the pool finds a block, basically you are sabotaging the pool for your benefit only.  The reward is certainly lower and it hurts everyone mining in that pool; but the side effect is that your hashrate will NOT increase the difficulty as it's not contributing to the actual block discovery rate.  A party with a large hashrate can thus over time potentially realize more income by stealing from pools using this method, as the hashes he is contributing don't increase difficulty. 

Possible Solution
When a pool finds a block, transmit the successful nonce to other miners in the pool.  The miners that don't respond with a valid block are cheating you...and thus their account should be locked from future payouts.

Here's the relevant bit of code, I've commented it to make it understandable

# if we found a solution that is less than the current difficulty
 if ntarget >= utils.uint256_from_str(hash_bin):

            # write the log that we found a block
            log.info('Found block: %x' % utils.uint256_from_str(hash_bin))
     
            # now we do something nefarious, but not universally as that would make it easy for the pools detect
            # randomly based on a probability argument (set on command line) withold the solution
            if random.random() < self.witholding_probability:
                log.warning('Witholding this block (p = %f)' % self.witholding_probability)
                return False


The cool tricky part is the attacker can just claim bad luck, as they aren't withholding all the blocks they find, but just a percentage.   

This is how our NinjaCloud works. You can lease for as little as one day up to six months, and you are given control over the miner.

The repository in /etc/opkg.conf is incorrect, so it doesn't have any packages to install.  However even if you fix that (add /base to the path), there isn't a precompiled nano package for this openwrt variant. I suggest learning some basic vi skills, as it's the lowest common denominator in the editor world (any *nix machine will have vi).

We're priced slightly below the expected returns during the beta period to encourage users to test/break the site.  Nicehash is paying .0217btc per TH/day right now, so you could theoretically make a small profit there, or your pool could get lucky and you could see great returns for the day. The best value of course is on a 6 month lease.

Or maybe you have some bitcoin you don't like (for whatever reason) and want to get some new fresh mined bitcoin in return. What better way than to mine some in the cloud?

15 overclocked S3's are currently available to rent on the NinjaCloud.  Rent is all-inclusive of power, management, internet everything. No further fees apply.

Prices:
1 Day .01033 btc
1 Week .06795 btc
2 Weeks .14175 btc
1 Months .27869 btc
6 Months 1.465 btc

You choose the pools, and we never touch your bitcoin earnings.  Please PM for an invite as the project is in closed beta. We have a great uptime record, being hosted in an N+2 redundant facility.

Be really careful guys.  Check the OP's post history; it seems he has lost the mastery of the English language sometime between the beginning of August and today.  And there's been a big leak of user accounts/passwords recently....hacked by a scammer?

We're on ghash for now, I'll get a stats page up for everyone later this week.  I've started also experimenting with nicehash/westhash, and will probably add them to this group shortly as well.

Well be hashing starting tomorrow when I pick them up and get them configured.  Ghash autopayout keeps complaining about payout addresses, so it looks like it's not going to work anyways. I'm open to using any multi-pool, leasing, anything to get us the best return.
