This guide is going to show you how to build an Ethereum Mining rig yourself which has two main steps - choosing and sourcing your equipment and then putting it together!Depending on times its probably going to take you a week or so to get all the pieces and then another half a day fiddling with configurations etc. Its the same as building your own computer normally but with a few extra considerations that mainly involve which GPU's you pick.If you don't want to buy mining equipment, You can also try buying a cloud mining contract with Hashflare or Genesis Mining.Your going to have to get hold of a fair few components and the costs stack up quite quickly: Another issue you can have with your graphics cards and your motherboard is that they just won't all fit in together nicely because of the spacing on the motherboard between the PCI Express slots.Fear not - you can use a GPU riser that is basically an extension cable for a PCI Express slot.Some graphics cards are really quite bulky so be careful when you are making your selection.

You can get a riser here.Alternatively you can source some of you components from gpuShack, on our second mining rig we are using the MOBO/CPU/RAM/SSD Bundle for 5 GPUs.Remember to use the promo code CRYPTOCOMPARE gets 5% discount off your purchase.As mentioned make sure your power supply unit can handle the Graphics cards and that you have risers capable of placing extra GPU's in a safe location.Make sure all the connections are in nicely and everything is held together firmly.A word on positioning.GPU's can get hot - especially if you overclock them so be sure to get the best bang for your buck - and to be safe to place your rig in a well ventilated area so it doesn't overheat.Once it switches on you need to make sure all the software is there for you to get it mining!The first thing you need to do is install an operating system on your computer.For the more technically minded there is linux Ubuntu but for the majority Windows is probably best as it automates installing drivers for your computer to talk correctly amongst all the components.

The advantage of Ubuntu is it gives you more options and its free!You can donwload EthOs which is a specifically designed APP for Ethereum Mining - you can read more about this here but its a great way of having a bespoke mining system for your rigs and GPU's to manage them!Once you have installed the operating system there are two ways you can mine: If there are any questions on how to get your rig up and running - or any part of the process - just drop us a line at the bottom of the article - our resident mining guru will help you out.You can also post in our Ether Forum and one of our community should be able to help you out!Also if we've got something wrong or it can be explained better let us know!Home / Open Air Mining / 6 GPU Mining Rig / Plug & Play 125Mh/s Ethereum ETH or... $3,800.00 Plug & Play 125Mh/s Ethereum ETH or ETC Mining rig 6x R9 380 4gb W/ ethOS Linux Ethereum Mining Platform.Out of stock Description Additional Information Reviews(0) Product Description ZCASHEthereum Mining System setup and ready to mine, suitable for experienced and first time miners alike Simply plug in ethernet and power, instructions provided to change the wallet address and optionally pool information and the system is ready to go.

For the highest hashrate per GPU, the answer is the AMD HD 7990 (minimum hashrate 43 MH/s), followed by the AMD R9 Fury X (minimum hashrate 28 MH/s).The HD 7990 was released in 2013 and is harder to purchase from stores as this series has been superseded by the R9 series released in 2015.Internally, the HD 7990 with 6Gb RAM consists of two AMD HD 7970 GPUs with 3Gb RAM each packaged together.Note that your Ethereum mining software will treat the HD 7990 as two separate GPUs with 3Gb RAM each, and miners with 2Gb GPUs have recently encountered some problems with the growing DAG file size 2Gb cards stopped working - 13/03/2016.From AMD HD 7990 vs AMD R9 Fury X, here is a comparison of some key features of the HD 7990 (left) vs the R9 Fury X (right): Other parts of the system The main part of the mining hardware is the graphics processing unit (GPU).Type "Ethereum" in the filter.In general, the best current GPUs are the AMD R9s.But the answer is more complicated.What do you want to optimise for?

Lowest upfront cost per unit hashrate?Lowest ongoing cost (upfront + electricity)?Best hashrate per unit electricity?Lowest heat (and electricity) per unit hashrate?And all this depends on the cost of hardware (it's all relatively more expensive in Australia) and the cost of your electricity (also relatively more expensive in Australia).For the lowest heat (and electricity) per unit hashrate I would say the R9 Nano.For best hashrate per unit electricity I would say the R9 Fury X.For the lowest upfront cost, possibly the R9 290.If you are considering the superseded AMD HD range, the HD 7990 gives you the highest hashrate as this is essentially 2 x HD 7990 GPUs packaged as one.It is harder to find stocks of these units now.I've gone for the R9 390X.You don't need a fast motherboard and CPU.AMD CPUs use more electricity than the equivalent (by performance) Intel CPUs.But AMD CPUs are cheaper than the equivalent (by performance) Intel CPUs.Your bill of materials will consist of: Build a list with expected hashrate and cost in a spreadsheet and work out the best for your situation.

Here's my meagre setup that produces 52 megahashes per second without overclocking, 63 with.Cost in Aussie dollars.It's not the best in many ways, but it works: It may be cheaper to buy ethers on an exchange.You may have to buy bitcoins with your fiat currency and exchange your bitcoins for ethers.Also, the number of ethers you can mine is limited by the "size" of your rig, whereas buying ethers will be limited by the size of your wallet.Here are two Ethereum mining profitibility calculators: The difficulty in mining ethers is going up as more people bring online their miners and the price of ethers in the future is uncertain.The Ethereum network will be moving from the current proof-of-work to proof-of-stake where the GPU miners will all become obsolete, and the date of the switch is uncertain but may be in a few months.It is very easy to burn out your GPUs - I've done in two, but luckily got warranty replacements.The first just stopped working after one day.And one of the fans got "sticky" in the second one after a few months.
