Hello folks,

I'm a first time miner. Please I'm about to buy a used mining rig from a friend of mine. He wants to focus on trading cryptos because he says its more profitable for him.

I will list the components of the rig below. If Electricity isn't a factor, do you think I should go ahead and purchase?

Rig is going for $2000 Undecided

Rig components.
Metal mining frame
5x 120mm cooling fans
2x amd Sapphire R9 290x GPU
3x amd Sapphire R9 290 GPU
1x 1800w mining PSU 80 plus gold
6x pcie risers v006
120gb SSD
4gb ram
Asrock h81 pro BTC motherboard
Core i5 CPU 4th gen

150mhs mining etherium on ethermine or nanopool

Rig is going for $2000. Any advice would be appreciated. Thanks.

2x R9 290X nets you around 5-6$ a day, if your electricity is 0$. see https://www.nicehash.com/profitability-calculator/amd-r9-290x?e=0.00001¤cy=USD

-As far as the 290 goes, it isn't listed on nicehash or any other profitability calculators, so i tried to calculate it myself.-

Someone should correct me if i'm wrong, but i believe the normal 290 has a hashpower of around 200h/s mining zcash? That'd be 3*1.31$ - 4$ a day by mining Zcash.

That'd be 9-10$ a day without electricity costs.

Your ROI would then be 2000/9 = over 200 days..

Note that i'm not an expert^
