Ready Made Ethereum Mining Rig 80mh/s

Ready made Ethereum mining rig, seller price $2,399 

This rig works perfectly for mining ethereum (ignore litecoin stuff).

What is included:

1. GPU: 4x ASUS Radeon R9 280x 3GB DDR5 (http://amzn.to/1WNdvmi) it looks to be very expensive now, i guess due to high requirements/sales, a used one can be bought for $200
2. Motherboard: MSI 970A-G43 (http://amzn.to/1TuzQia) it can support up to 4 GPUs max. $75
3. CPU: AMD Sempron 145 2.8Ghz (http://amzn.to/1qEOzPt) $75
   
4. SSD: 8GB USB (http://amzn.to/1WcMEQ3) $20
   
5. PSU: There are no details about this but it should be a 750-850 watt or a bit more. (http://amzn.to/1XrMNhB) from $80 to $125
6. Power Switch: Yes (saw it in the screenshots) NOTE: usually mouse and keyboard are not included, buy one from here: http://amzn.to/1sMTgIW

What it can do and is it really worth the price?

• It can mine around 80 mh/s (around $300 profit monthly) out of the box, overclocked can do much more but will be needed a more powerful PSU
• Watt consumption ill say it will have a max of 850, if not overclocked.
• You will get the money back from your investment in 8-9 months.

Profits:

Calculated for: hashing power 84 mh/s, power consumption 850w, cost per KW/h $0.11, 1 ETH = $ 14.12

• Daily: $ 9.41 – Ξ 0.8253 / power cost $ 2.24
• Weekly: $ 65.86 – Ξ 5.78 / power cost $ 15.71
• Monthly: $ 282.26 – Ξ 24.76 / power cost $ 67.32
• Yearly: $ 3,434.12 – Ξ 301.22 / power cost $ 819.06

What if you do it yourself with the same parts?

The total cost will be around  $1500 if you can get the GPUs for $250 each, if not as seen on amazon the costs for a brand new one varies from $500 to $600+ and then the total cost for one rig will go up to $3000, but of course you can use a different GPU like R9 380X (http://amzn.to/1WcOFf0) and the price for this rig will be lowered back to $1500, unless you are not a tech guys and really have to buy a ready made one.
