I actually just built a new rig.

- MSI H310-F Pro Motherboard
- 1,350 Watt PSU
- Intel Core i5 9400
- 16GB RAM
- 120 GB SSD

- 2 x Radeon RX 570 8GB
- 4 x Geforce 1660 Super 6GB

I'm probably going to return the RX 570s. The 1660 Super performs much better.

I installed AwesomeMiner on my desktop and initially installed Ubuntu 18.04 on the mining rig with the *nix version of the AwesomeMiner Agent. That really became more of a pain than it was worth. After installing Windows 10 and the Windows AwesomeMiner Agent on the rig and running the benchmark testing, I can probably make about $25 a month after paying electric costs of $0.13 / kW.

If I return the RX 570s and get 2 more 1660 Super, that should go up to about $35 a month. Which means it will be about 3 years before I recoup the costs of the hardware....

I wish I had been paying more attention to crypto 5 years ago.

Now I'm looking for decent pool software to start my own pool.
I have Yiimp running with no coins installed yet.

If you're just interested in checking it out and playing around, just download AwesomeMiner on your desktop and give it a shot. If you're looking for serious profits you'll need at least $2k so you can invest in an ASIC and hopefully recoup that cost before mining Bitcoin becomes a moot point, if it isn't already.
