With ETH (ethereum) hitting going over the $300 mark, I have decided to try to build an ETH GPU miner. Researching what it takes to build a miner seems to be pretty simple. You need GPU's, motherboad, processor, memory, a hard drive and a case. Sounds pretty simple and worst comes to worst I have a bunch of very sellable or re-usable computer parts.
My HOPE is that ETH will have a growth rate like bitcoin. Bitcoin is currently ~$2567 and was trading ~$400 around a 1.5 years ago.
Motherboard: MSI Z170A M5 motherboard ($149.99 NewEgg)
I chose this motherboard becuase it was fairly well known and supports up to 7 GPUs.
Processor: Intel Celeron G1840 ($50 ebay)
A cheap processor that works with the MSI motherboard.
Memory: Kingston 4GB ($30 NewEgg)
Something cheap, we don't need a lot of RAM
Hard Drive: 278GB Crucial SSD (Something I had on hand, ~$99 NewEgg)
We will need just enough space for the OS.
GPU: GeForce GTX 1070 (Various sites ~$400)
This was not my first choice for GPU. I was trying to find ASUS RX 580, but anything close to these cards are backordered for who knows how long.
Power Supply: Corsair AX12001 ATX ($329.99 Fry's Electronics)
This is a solid, efficient and has enough cables to power 6-7 GPUs.
Operating System: ethOS ($39)
I had to modify this to work with a NVIDIA GPU, so I will be converting to Ubuntu later.
Case: 3 drawer storage cart (Bed Bath & Beyond - $25)
I eventually plan on buying an open air frame or making one, but this should do for the meantime.
Total Cost: ~$2,993.98 or ~8.55 ETH
This rig should produce around 156MH/s and 2.4 ETH per month.
If ETH stays around $350 it will pay itelf off in ~3.5 months and should produce ~$10k per year.
(NOTE: I am not factoring in cooling or power costs)
