How to build a crypto mining rig in 2020 to earn Bitcoin and Ether
Mining with home rigs is back, so here’s what those interested need to know to put together their own rig at home.

In a time of global crisis, a pandemic, and a generally unstable political and social environment, cryptocurrencies have shown remarkable stability. Moreover, the pandemic-induced economic downturn played into the hands of the industry by not only attracting professional cryptocurrency traders but also reviving mining as a way of generating passive income.

It is not surprising that countries experiencing difficult political and economic situations have witnessed a boom in the purchase of GPU cards in recent months. In the region of Abkhazia, where all crypto activities have been illegal since 2018, citizens spent more than $500,000 on mining equipment over a period of six months.

Another factor that has worked to further popularize mining is strong crypto prices. Bitcoin (BTC) has risen by almost a third, while Ether (ETH), the most popular currency for mining, has added $150 to its price and the decentralized frenzy has meant that gas fees have reached unprecedented levels.

So, here’s how to design a cryptocurrency rig — and an exploration of whether it needs to be done at all, given all the associated risks.

Mining rig components
A cryptocurrency mining rig consists of a computer that has many graphics cards but no monitor. Computer cases are filled with GPU cards, a power-generating unit, a motherboard and a cooling system. If a monitor is connected, it can become a regular computer where a user can open a browser or play their favorite video game.

The rig is connected to the internet, and thus, the blockchain network. The network operates by itself to conduct monetary transactions using the power of the graphics cards. To be more specific, a mining rig consists of:

An ordinary motherboard, which has the capability of linking to a number of connectors for GPU cards.
A hard disk drive, or HDD, with 100 to 250 gigabytes of memory to house the cryptocurrency wallet, with an Ether wallet usually taking up 25 GB and a BTC wallet requiring 50 GB or more.
Several GPU cards, which are the most important components in a rig because they are the base that defines the cryptocurrency that a user will mine, along with their future profit and its timeline.
A power-generating unit. A rig with four GPUs often requires more than one power unit. Usually, miners have a few 750-watt units connected together.
A power adapter for GPU cards. Video cards are connected to the motherboard using special extension cards called “risers.” There are many different types and models of risers, but the PCI-E 1x version 006 is the most popular.
A power switch.
A cooling system, and it’s preferable to have several coolers to provide additional airflow.
Another important detail is the frame for the rig. It is better to make a frame out of wood or aluminum. The size of the mining rig will be slightly larger than its frame due to protruding parts, adapters and a cooling system. For example, a seven-GPU rig will be approximately 21 inches wide (53 centimeters), 12 inches deep (30 centimeters) and 12 inches high (30 centimeters).

After purchasing all the components of the rig, it’s time to design it, which is a rather easy task for a person who has experience with computer hardware. Additionally, there are plenty of guides on YouTube.

When a rig is ready, all that needs to be done is to install some software — i.e., to choose a program for mining the currency of preference. Another way is to find a mining pool, which is a popular way to mine, as it’s becoming harder to do so individually due to the rising complexity of crypto mining. There are also some tools available such as TeamViewer, for remote control, and WatchDog, which automatically restarts the system if the program freezes.

GPU card in the top
As a rule, one rig should include four to seven video cards — it’s a number that will not go beyond the framework of a stable operation, although there are exceptions. Miners can connect 10 to 15 GPU cards to one motherboard, but seven is the optimal number because Microsoft’s Windows 10 operating system can detect only this number of cards. But there is a solution: specialized mining software based on the Linux kernel. In that case, the key is to choose the right motherboard, such as an ASRock Pro BTC+ series or similar.
