Description:

12 GPU RX470 open air mining rig - 367 Mhs Ethereum. Used - good condition all cards purchased brand new as well as systems components, power limited currently only drawing 1555w, never run above 65 Celsius due to temperature throttling settings on OS, runs on average between 45 - 55 Celsius. Collection only.

Get on the crypto-currency bandwagon and earn a passiveincome! With cryptocurrency back on the increase again, Bitcoin is projected to break 100k USD mark by the end of this year (Max Keiser - RT report) with an all-time high and the rest of the crypto currencies follow. I have a professionally custom built 12 card AMD RX470 mining rig currently mining at 367Mhs drawing 1555w (see photos of Amp reading and Voltage with a Fluke). This mining rig has been fine tuned to maximize hash rate with lowest possible powerdraw. Currently mining Ethereum, however can be configured to mine ALT-coins or auto swap mined Ethereum for Litecoin/Bitcoin ect.
The reason I am selling is due to space limitations. We moved into smaller accommodation and are limited for space. I have had this running without issues for the past year, it is stable platform running ethOS(linux based kernel specialised mining software) and rock solid. The frames are stackable and I have this currently configured like this. The system comprisesof the following components:

Motherboard ASROCK H110 Pro BTC

CPU - Intel Celeron G3930

Memory - 8Gb Corsair Select

Samsung USB memory stick with licensed ethOS operating system

Stackable aluminium frame with acrylic sheet

Risers x13

Corsair cooling Fans x8

Belkin surge protector

2x Seasonic Snow Silent Power supplies 1050w (10 yearwarranty)

GPUS:

10 x Sapphire RADEON RX 470 MINING EDITION 8GB (mixed memory- Micron, Hynix)

1x Sapphire RADEON RX 470 MINING EDITION 4GB - (Samsungmemory)

1x ASUS MINING RX470 4GB (Hynix)

The rig has space to host an additional card, as the motherboard will support up to 13 GPU. Currently running 12 GPU with an additional riser to support 13th card.

The system runs on average at 48 Celsius and temperature is limited through the operating system ethOS to 75 Celsius, at which point thecard shuts down. It throttles back and lowers power draw to decrease on temperature as it gets closer to 65 degrees Celsius. The key to longevity on the graphics cards is limiting the heat which is done through adequate cooling and lower power draw. I have (18" and 20") industrial fans drawing cool air from the outside and circulating through built in on-board Corsair fans and then an extractor fan to remove heat.

With the Ethereum back on its way to its 2017/2018 high of $1,432.88 USD projections are it will pass this by miles following Bitcoin on upward trajectory. Get on the crypto mining bandwagon early rather than late when all the graphics cards are ridiculous prices again and demand outstrips supply. A simple calculation shows that based on (date 24/06) hashrate and Ethereum mining difficulty, this rig produces 0.841543691813063 Ethereum per month which transposed onto the high prices of $1,432.88 USD equates to $1205.8311 per month (not taking the costs of electricity into account) - see attached screenshot from etherscan.io (for display purposes only and potential earnings, as variables change on a day to day basis like Ethereum mining difficulty, electricity costs and price of Ethereum).

I have five more crypto mining rigs producing a total of 2250 hashes on the Ethereum network including this rig. I may consider selling the entire mining operation for £40k ono and can provide photos of the complete systems. The other rigs have more expensive graphics cards and higher hashrate than this particular system, hence the price. Collection only, I will provide support on an ad-hoc and reasonable endeavours basis for up to 6 months after purchase. Though to be honest, the ethOS support team is quite good and helpful.
