Well, it’s been a very long time since my last post but I am back, better than ever!
I took a 3-week trip to South Korea in January to see my parents and during that time I couldn’t wait to build rigs again. But during that 3-week off, I did a whole lot of research on how to make even more efficient litecoin rigs than using milk crates.
First, I considered using square aluminum tubing, which some of the miners are using but the cost of using aluminum was a bit too much (near $50 range) and also aluminum conducts electricity, not really the best choice.
Then I had an idea, make the same rig using square wood!
After a long trial-and-error (of building around 5 different wooden frames), I finally found a sweetspot, and came up with my own design that will fit 6 graphic cards while giving it very efficient air cooling.
I am sure you will come up with your own design one day but for now, this is a great design to start with so, have a look!
UPDATE: I’ve started selling these wooden frames online for those of you without power tools or need a fully-assembled frame, you can get them over at OpenAirFrame.com.
Step 1. You will need 6 pieces of 3-feet square wood. You can use other sizes if you want though since we will be cutting them anyways.
For this HighOnCoins rig frame design, you will need:
- 4 22″
- 2 20.5″
- 2 8″
- 2 7.75″
- 2 4.5″
- 2 14.5″
That’s all the wood you will need to build the frame, which costed me around $9. So under $10, you can build a sturdy frame that will run 6 graphic cards with nice spacing. You can also modify this design to make it longer if you want. (But I find that 22″ is perfect as anything longer will require you to use longer-sized PCIe risers, which are hard to find these days. This design will use 2 long risers and rest can be medium/short-sized risers.)
Step 2. Once the pieces are cut, your first job is to make a “rectangle” using 2 22″ pieces and 2 14.5″ inch pieces as shown below:
Step 3. You will need to first choose which of the 22″ wood to be the “front” of your rig. That’s where the motherboard USB slots will face, to the front. The 2 middle pieces are the 20.5″ pieces that will go where your motherboards screw slots go. For me, this was 6″ and 8.5″ from the front 22″ piece. (Just lay your motherboard and find out where the screw holes go, that’s where the middle pieces go.)
After that use the 2 8″ pieces for the front 22″ and 2 4.5″ pieces on the other side as shown below.
Step 4. You can use the 2 7.5″ pieces for the side of the frame then simply put the last 2 22″ pieces on top to finish off the wooden frame.
Step 5. To put the motherboard, use the similar method I used with milk crates here in Step 10, then use zip ties to tie it down. (I screwed holes where the motherboard screw holes go.)
Step 6. For securing power supplies, lay a piece of wood that will go on top of your rig, then screw a hole at the end of the power supplies so you can get zip ties to go through.
Step 7. You can use Add2PSU here to connect the 2 power supplies. I also find it helpful to pre-connect all the PCIe cables before putting the graphic cards on it.
Step 8. Voila, when you are done, be amazed the results you can have under $10 of wood!!!
Overall, this took me awhile to master as I am not an expert at wood-making, this is just a hack job that I had to learn so I can build more efficient rigs. But I do see there’s similar frames being sold on eBay for $60-80 and you don’t really need to spend extra money on that, just build it yourself.
At first, it took me 4-6 hours to make a wooden frame but now it only takes me 20 minutes!
Definitely, wooden frames are the way to go if you plan on making multiple rigs as they are much more efficient than milk crates and also very easy to work on your rig when something goes wrong (such as swapping graphic cards/risers).
You can use this rig frame to mine all kinds of coins including Litecoins, Dogecoins, Fastcoins, etc…etc… enjoy!Like my tutorial? You can send me coins!
