So I have sold off the last of my S5's due to the release of s7s and a very fast declining return. After a year of mining I have to say its an interesting endeavor that can consume a lot of capital but the return is decent if you don't pay for power.
That being said I have decided to invest in an ETH miner and sourced the following parts.
New
- MOB:
ASRock 970 Extreme3, AM3+ (plus), AMD. Probably a bit of overkill but the price was fair.
- HDD:
F5 2.5" SATA 32GB Kingfast MLC SSD. My thoughts are to run GenEthOS on the SSD.
- Riser:
4x USB 3.0 PCI-E PCI Express 1x to 16x Extender Riser Adapter 
- RAM:
Corsair Vengenace DDR3 1866MHZ 8gb (2x4gb). Again probably overkill but the price seemed good and I wont have to worry about memory thereafter.
Used
- PSU:
1200 watt EVGA Supernova P2 Gold. left over from S5 operations.
- CPU:
AMD Athlon II X3 405e 2.3 GHz Triple-Core CPU Processor Socket AM3
- GPU:
Asus R9 290x 4gbTotal cost of inital package was about
. I plan to source another 3x 290s in the
range over the next month. From there my assumption is I should be mining about 6ETH/Week per 290x based on this calculator (
https://badmofo.github.io/ethereum-mining-calculator/).
Total cost recovery on the current system (1x 290x) at current rates is currently about 5 weeks. based on the Shapeshift Instant Rate 1 BTC = 54.02439024 ETH.
Thoughts on my setup? I still need a case, I know.
