Many of my Facebook followers know that I am into four things right now, fishing, websites, youtube, and mining bitcoin. So, I thought I would make a small post and share a few of the items I would buy today for a mining rig.
Yes, I know that this will be low traffic, but hey it will be a fun read for my Facebook friends and youtube followers.

What is the Goal?
My goal is to build a mining rig that is cost-effective, power-efficient, and produces enough money to make it worth the effort. I need to start with cards that I can get at a fair price but are new enough to have staying power. I don’t want to buy a card and have it not be able to mine anything of value next year.
Some cards are power-hungry and this can be an issue but the overall hash rate to power is the main concern when picking a card. A good card needs to mine at a fair speed per watt.
Finally, why build a mining rig that doesn’t make any money, what a waste of time. I need to make at least twenty dollars a day or I could spend my time and money on a new website, lol.
Picking a Motherboard
My biggest concerns when picking a motherboard are compatibility, ease of use, price, and durability. These factors are in no particular order because they are all important, so I wrote them down as they came to me.
I want a motherboard that I buy today to be compatible with everything that is being produced today. It would suck to buy a board that would not work with the top-of-the-line GPU.
Easy setup is a must, because who wants something that is hard to get going and maintain. A dedicated mining board with the latest drivers should do the trick.
Price is a big concern because this is all about making a profit. No need to spend more than you need to on some high-end gaming board that will require adapters and updated drivers to mine eight GPUs.
Finally, I want something that will work for years to come. As any miner knows it is all about getting long life from your mining rig that makes it profitable. most miners plan on their rig running nonstop for three years.

If this package is not available or you would like to use a different PSU Click here for a US listing for the BTC-s37. Also, a great PSU for 8 medium-powered cards or 4 high-powered cards is the Mystic mining PSU, but it is 240 volt. For low power options the Corsair RM850x, 850 Watt, 80+ Gold Certified is a great option for 120 volt systems. it is budget-friendly, reliable, and you can easily ad another to increase your total wattage.

Of course, any good tools that will work with your build without damaging the parts is are good tools. However, we have a tool kit made for computer and GPU maintenance.
This set includes all the tools you should need to build and maintain your rigs.
- anti-static wristband
- opening tools
- scrapping tool
- prying spudgers
- screen removal suction cup
- driver and bit set (screw driver)
I can’t one paste is better than any others but this is the one I used on my last round of maintenance, and it worked great.
Adding more GPUs
If you are going to add more GPUs to your system you are going to need a PCIe splitter, risers, and cables. Don’t forget to calculate your PSU usage and don’t go over 80% without overclocks, just in case.
- splits a PCIe 1x slot to 4 PCIe slots when you add risers
- improved heat sink/cooler
- Standard USB 3.0 to riser plugs.
- Removable slot cover
- 16X Riser Card V011-PRO Version PCIe riser Card
- 10 capacitors
- Multi-interface power supply – Dual 6PIN ports, side or end connector
- 60 cm USB 3.0 cable
Note: Throw the SATA to 6 pin connectors in the garbage as they are not suitable for mining
- Conector A – GPU 6 pin female ; conector B – 2 x Pcie 8 pin (6+2) pin male;Genuine new copper cores
- Convenient solution for adding two extra PCI Express connectors to your existing power supply
- 6 Pin female end to connect to the power connector of the power supply and two 8 Pin (6+2) male ends to plug into the video graphics card or riser power
- Compatible with 6-pin & 8-pin graphics cards from popular manufacturers 9-inch (23cm).Gauge: standard 18AWG
- 16 inch 6 to 2×6 (PCI-e 6 pin ; Conector B – 2 x PCIe 6 pin male)
Build Frame / Case
There are many frames that you can use to build your rig oo when using the BTC-s37 motherboard but for most average size GPUs I prefer no frame at all. A simple piece of pine can be bought from your local hardware store or lumber yard.
Mounting the board can be done with screws and 20mm spaces or you can use motherboard standoffs. I like you put motherboard standoffs down the middle and plastic spacers along the edges.
Supplies I purchased
- Nylon Standoff Motherboard Assortment Kit
- PCB Board Mounting L Feet with Screws
- 150Pcs 10 Sizes ABS Plastic Round Spacer Assortment Kit
- 50pcs ABS Round Spacers, Washers Assortment
When using high heat GPUs like a 3090 a case is almost a must-have for good airflow. High flow fan like a 4 pin ASIC fan will connect straight to the motherboard and provide all the airflow you need to cool your cards.
Another issue for large GPUs is support, adding a piece of aluminum angle bracket makes a great mounting bracket. Do keep in mind that everything needs to lineup, so test fit your board and GPUs before securing them.
Ventalation / Cooling
Cooling is one of the main concerns with any type of mining machine. The main focus of my cooling has been ASICs be the same approach works just as well with GPU rigs.
I popped out a window, installed an industrial barn fan, added a screen and security bars as my primary form of negative pressure, aka exhaust. Then I built a box out of 3/4 inch plywood with shelves as part of the structure.
I have most of my old GPU rigs in Rosewell server cases on an old meat rack with wheels. You can see the rack on the left edge of the picture above. When I am not working on the ASICs or GPU rigs I move the rack next to the ASICs.
By placing a piece of plywood from the top shelf to the top of the rack most of the heat goes straight through the vent box and outside. During the summer I do run an input fan to draw air from a vent system located in the shade.
BTC-s37 Motherboard PCIe Slot Order
Most people know that your slots don’t load in the order that they are arranged on the motherboard. This is one reason many people prefer to load identical cards in one mining rig, including me.
As of the time of this post, I could not find a slot map online so I got busy and mapped the board I have running. My process started with getting out blue painter’s tape and labeling the GPUs with their current HiveOS GPU number. The motherboard is labeled PCIe 1-8 so on a piece of paper I made notes of the location of each GPU.
Finally, I shut down the rig and moved GPU 6 into each of the empty PCIe slots then noted the new GPU order in HiveOS. Note: GPU6 is the only Powercolor 6600 I have so it is easy to see in HiveOS.
Here is the results table:
|PCIe motherboard slot # (1-8)||. GPU # (0-7) .|
I have not had the chance to test it on another board but plan to when I get to my buddy’s mine.
Here is the slot order written out if it helps you: 1, 3, 4, 5, 6, 7, 0, 2
This should be a simple build that you can put together and make a wooden frame out of 2x1s with no issues. Flash HiveOS on your USB sticks and make a duplicate in case it crashes.
