I'm thinking about selling my entire GPU mining operation as a turnkey package, if the price is right. Since I'm simply toying with the idea, I wanted to post and get a gauge interest.

Here's what would be included:

1). 90,000 kh/s mining operation, fully active and transferable once payment is received, the operation has been active for over 6 months
2). You own all equipment running in this operation:
       - ~(52) 7970s - Mostly Sapphire
       - ~(98) 7950s - Various - Sapphire and MSI Twin Frozr mostly
       - (40) complete systems with aluminum framed cases custom made to fit (2) system boards and up to 8 cards
       - Remote controlled APC Switched PDUs - Allows remote hard reset for lockups
       - All network switches, and backbone equipment
       - High end video camera unit to monitor space
3). Transfer of 1 year lease that will be up in 12/2014 - This space has .048 kw/h power, along with 400 amp - 3 phase service. Currently maxed out, but new service can be added if you want to invest in upgrade of service - Monthly cost of lease: $350 plus electrical, which given the cheap power, it runs less than $1,500 / month for power. Add $150 for insurance / internet service monthly (this is up to you, but recommended)
4). To calculate current ROI, you would use the 90,000 kh/s number, 45,000 watts, 4.8 cent kw/h, and you'll see it's making about $1000 a day, with difficulty growing fast. Currently, it takes in 32-35 LTC (edited to remove BTC typo, I wish it made 30-35 BTC a day!) per day in a pool.


Since most people would not be local to me, I would be willing to be on call, for a pre-determined fee to fix any issues on your behalf. In the Summer, adding cooling is probably going to be necessary as the operation was recently ramped up.

It wouldn't be going for a bargain price given the current cost to mimic this operation both in time, cost and availability of equipment.

Starting bids in an auction would be the BTC equivalent of $200,000 USD.

There are four cases (8 systems) missing from the attached picture, as I have them operating at my house to provide heating during winter months.

I realize this is not limited to Coinotron, but occurs on all pools, but what is the reason for a large variation in hash rate?

I have 9 rigs, 25 GPUs currently, and I setup worker threads for each machine so I can better track how each one is operating. My kh/s on my side in CGminer  is anywhere between 16,900 and 17,500 and the Wu/s number is within 86-95% of that number.

However, when I check on Coinotron frequently, it will show a range anywhere from 14,500 to 17,900 at different times. I've checked my side and it doesn't appear to be a problem, so I'm wondering if this is by design, or if there is anything else I should look at to keep the rate steady on the other side. My payout is close to expectation, so I'm not overly concerned, just very curious.

Well I double my hash rate over the next month, I want to make sure everything is maximized.
