Building a dedicated LTC mining Rig

[xpl0iter]

Hello Guys,
I have been thinking whether to go with buying bitcoins/litecoins or go by building myself a dedicated mining rig.

I think I will go with building a dedicated mining rig. I have a budget of 60,000 INR. Can anyone possibly help me in finding the best mining rig which is possible to build under this budget. I have no other uses with this system.

I think I will be able to easily make around 15,000+ INR per month when I checked with the LTC profit calculator. Let me know if I am wrong in anything.

For 60K INR, you should be able to get a decent setup for BTC itself.

Atleast at the current difficulty.

After adding a graphics card and strong PSU for mining, I learned that the online calculators for power and profit were misleading. At least I can game on my 7850 and I can turn electricity into crypto currencies (my electricity tariff at 8 cents/4.5 INR per KW/h is too high to sell crypto currencies at profit.)

I only trust http://litecoinpool.org/calc for ltc earnings based on hashrate.

For dedicated pure mining, one or multiple 7950s is best in a rig without side casings.

How much revenue do you think I will be able to generate per month as of now?
Also can you please suggest me a configuration?

So are you saying even with a good mining RIG the electricity charges will be more than the revenue I earn from litecoin mining?

EDIT: What do you think about this card: http://www.flipkart.com/sapphire-amd-ati-hd-7950-3gb-gddr5-boost-3-gb-graphics-card/p/itmdfyygkk2zwpjk?pid=GRCDC2QTBPZHV8HQ&icmpid=reco_pp_hSame_graphics_card_1

Try this calculator, it seems to be realistic for hardware calculations (it's for btc:)
https://bitclockers.com/calc

The Sapphire 7950 seems to be a good buy. I think the normal top hash rates for 7950's are 600 Kh/s (6,500 INR revenue per month at current difficulty and prices for ltc.) You get more bang for the buck with 2-5 cards but I'm not sure where to get PCI-E risers in India.

My calculations with electricity and hardware cost may be off. I'm either overestimating electricity costs per hour by a factor of 3 or the calculators are underestimating electricity costs by a factor of 3:

A 300W system takes up 1.08 KW in an hour. 1 KW/h for me costs 0.08 usd
If I run the system for 24 hours, I should pay 24 * 0.08 which is 1.92 usd
The calculators say 24 hours of 300W at 0.08 usd KW/h is only 0.58 usd

A 300W system can only take 300W in a hour. thats 0.300KW, not 1.08KW

Well then my price estimate of 0.08 usd/KWh is wrong then (edit: 0.27 usd per KW/h would be the price of my electricity.)

I live in Kerala and I entered 5 60W lightbulbs here http://www.kseb.in/index.php?option=com_wrapper&view=wrapper&Itemid=72 (consumption calculator) and I got 216 units for one month of use which is 3,240 INR (15 rupees/unit since I'm already on the highest tier of electricity.)

I get 2,840 INR worth of litecoins if difficulty and exchange rate stays the same for 3,240 worth of electricity. That's 268 Kh/s at an overestimated 300 W.

That said, someone on give me ltc pool who has an ASUS 7950 said that their card can touch 700 Kh/s. My ASUS 7850 can touch 350 Kh/s (350 Kh/s would get me 3,696 INR of revenue which is only 450 profit a month) when overclocked (the normal top rate for a 7850 is 330 Kh/s) but it gets too hot since I'm using a closed, micro atx case from iball (at least the cards fit in there.)

MSI and Gigabyte are good choices for 7950's with MSI being better at power consumption (info I overheard on the g-m-l irc channel.)

Right now mining BTC is more profitable; may change soon though.
