The high MB and power supply cost is due to the 7 video cards. Do you not think it's worth it to get 7 cards in one rig?

depends on the space you have to work with, and the noise and heat you can tolerate.

it's great to increase your cards per rig; but i go for stability, and i personally prefer 3 or 4 cards per setup (slightly underclocked, undervolted), which is more manageable for me than trying to get 5 or 6 cards rock solid stability. i want to be able to walk away for weeks and not have to intervene.

regarding expense: if you are building open rigs 2x500w is cheaper than 1x1000w. for video cards, keep in mind before the november price increase 7950s were $200 and 280x were $300; See if you can buy direct or backorder from your supplyer rather than ebay or craigs. things will change quickly for 2014, so avoid paying for overpriced cards.

except for video cards, i'd say if you shaved off whatever you could by going with the cheapest everything you're in the ballpark for break-even.

i've been adding rigs to my farm whenever the prices and inventory present opportunities. make sure you don't overpay for video cards; some people make more money on video cards than mining.

Unless you plan on doing other stuff with the system, I would go with a much cheaper MB and CPU... Even your PSU price is too high :]

Go with an AMD 145 CPU, a MB that costs no more than $100 (yet has enough PCI slots), and maybe $230 for the PSU (EVGA G2 1300's or Rosewill 1300's are around that price)

If you are comfortable with Linux, a mining distribution (like BAMT) is free, other than the cost of a 4GB or larger USB Drive

Riser cables can be purchased for $10 to $20 a piece depending on if you want powered or unpowered... 1x or 16x

Of course, if you also want to game / use the system as a "normal" computer then a lot of this doesn't apply... otherwise it's all about getting the cheapest parts that still work reliably (other than the high-end GPU's of course)

As for profitability, that's something that is much harder to predict. A few weeks ago a "normal" rig of 2.5 MH/s or so was making >$50... a few weeks before that you were lucky to make $12 a day... I think $15-20 (not including power costs) is perfectly reasonable, however, I say that with not much confidence Tongue

I'm about to pull the trigger on purchasing the parts for a mining rig and was trying to work out profitability. Using coinwarz and middlecoin I came up with these figure.

Do you guys think I'm in the ballpark?

Am I seeing it right, 2100.00 for 2100 k/h? seems the ratio is high, you should be able to get more hashes for 2100.00.
