Is there a calculator that measures this?

Here is one tool:
http://www.alloscomp.com/bitcoin/calculator.php

Your 2100mhash @ current price 4.33$

Coins   / Dollars
per Day   ฿1.53      $6.65
per Week   ฿10.74   $46.52
per Month   ฿46.65   $202.0

Given a perfect mining environment where none of the cards go down, cables fry, cards overheat, mobo slags or PSU blows. And you keep it running 24/7/365, your wife never notices that your project room is at 118 degrees in the dead of winter, you stay sane with the sound of all those fans blowing at 100% 24/7.

And that you can afford the electricity, or have a really long extension cord to the neighbor's house to keep it all humming along.

But, yes, around 1.5-1.75 btc per day is about right. Merge Mine it and you might even tweak up past 2 btc.

Liquid cooling solves most of the first problems you mentioned.

Living in an apartment that pays for your electricity solves the next one.

I want to figure out if I can make this more profitable.

I wouldn't mind running 100 rigs x 2 gigahashes per second

But you need to know your power cost.  You can easily mine at a lost if your MH/Watt is bad.  More gigs mining at a lost means more losses.

power cost is irrelevant, I live in an apartment that pays for my electricity

This is currently what I am planning on building/making/ordering from newegg soon...

This is my current setup for bitcoin mining, the emphasis is really on the graphics cards... please review...

I PLAN on using this case: http://www.overclock.net/forum/newestpost/1144824 and liquid cooling from koolance on top. I'll probably only get 1 monitor and share between comps, am planning on buying/making up to 10 of these rigs.

Am I missing anything?

You don't need a HDD.  Just run BAMT off a USB stick.
And 2G of RAM will do.
EDIT:  And if this is just for mining, your CPU is an overkill.  Just run a sempron.

if you are in an apartment then you are going to hit the limit on a single circuit at some point.  maybe three to five of those rigs at best.

Merci beaucoup for the comments, will be changing my cpu and mobo now.

Alright. I found myself a better motherboard, capable of 6 video cards, should be noteworthy! I will not be replacing the cpu though, it's cheap enough at $250.

This is what it looks like right now, please give me some advice...

With 6 high end video cards, I am sure to be way more than 2.1 Ghash... is there some way for me to figure out how many gigahashes I can produce with these 6 cards before buying?

Okay I am a little disenchanted after doing some calculations... This rig costs $4,329 and only makes about $9,000 a year... If I were to multiple this by 6(or 30k... which is how much rigbox costs)... it would cost 30k and only make $54,000/year.


NOW RIG BOX by butterfly labs costs 30k, produces 50.4 gigahashes and makes $121,000/year.

OBVIOUSLY making your own rig is not the best option, does anybody else agree with me?

Note BFL has yet to ship them, there's no warranty (IIRC), they're unproven (may be over-heating, and if it fails, you're out $30k as opposed to paying $15 in shipping to replace a gfx card), and likely will have pretty darn low resale value once Bitcoin mining rewards start becoming less significant. Along with that though, you won't be making either of those amounts per year. Bitcoin block rewards will be halving in ~9 months.

Your non-FPGA components aren't cost-efficient for mining either. You really only need one core CPU, 2gb RAM, a basic MoBo, a $10 USB stick to toss Linux on, and 7970s are more for $/W than $/MH performance.

You should probably also consider your landlord may kick you out if you're using >$200/month in electricity. :x

What the hell is bitcoin mining rewards?

Doubt landlord will do that.

okkkkkkkkk i just read about mining rewards lmao

I'm not even planning on joining a pool and you started talking about it here

It's not pool-specific. Bitcoin will halve the block reward from 50 coins to 25 coins in ~9 months.

oh OKAY so you're saying my income will be halved? If so, I don't mind..

You dont mine x blocks per day. You produce x hashes per day. How many BTC that gives you depends on difficulty. Just assuming difficulty would remain stable is not very reasonable is it would imply the exact same hashrate would keep mining even at half the profit. Thats not gonna happen. I dont think anyone really knows what will happen though.

it's useless to measure $$$/day. BTC value can change times in just several minutes. W/o any "visible reasonable reason". The only thing you should count is "when should I stop mining" or "should I stop mining if rate drops down to ...".

Surely, with free electricity - it's not an issue even if btc costs 0.1$, tjough your hardware may burn out sooner than you get its value back

butterfly labs better have warranty of some sort, they seem professional enough

Keep an eye out on how much you'd make back selling the hardware.  Figure out a time/price to sell it at.  Than figure that into your profit equation.

Example:

Buy rig for $1000
Make $50/month
Sell equipment in 6 month at 80%, 1 year 60%, 2 years 30%

Bitcoin becomes unprofitable to you in 6 months
$300 bitcoin profit
- $200 hardware loss
= $100 assumed profit (if the coin was somewhat stable)

This doesn't assume many other variables either, but you don't seem concerned.  If you can't resell, you can't pull out of the mining game when you need to.

A typical apartment is set up with 60-100 amps worth of power. Given the usual loads of a person living there, appliances, heating and cooling, lighting, etc. that capacity has room for maybe 2 rigs of the level you are designing. Beyond that you will be drawing way more than can be delivered through you infrastructure, and you will be in a state of permanently blown fuses/tripped breakers. It is unlikely that your landlord will upgrade your apartment to a 200 amp service, or install a transformer for you. Don't spend the money before you know what you can realistically install. I am pulling 2.5 Ghash in my home, where I do have a 200 amp service, and pay $0.08 per kilowatt. My rigs add $200 per month to my electric costs. You can be sure that your landlord will be aware if you are suddenly drawing four or five times the power that any other apartment does, or if you are tripping breakers all over the building, and yes, landlords can and will pass that unusual expense along to you, or toss you out.

There's no need to think about anything like that yet. Also if anything like that happened, I'll just take it as a loss.

Never had a problem yet, already running several comps at my house. Pretty sure I can just pay for elec when needed.

It's not paying for it, it's more a question of getting it to come through the wires without blowing the system, or causing fires. The capacity of the wiring in your apartment will accommodate several computers, yes. Chances are, those computers are not each drawing 900-1200 watts continuously 24/7, kicking most of the energy back into your air volume as heat, and created a steady massive load for your service.

Systems can handle random spikes in usage, and when it is too much, a circuit breaker trips. When that usage is a continuous spike, and the breaker trips (you hope) there exists too much load to reset, and then, no juice to make the money machine work. You just can't squeeze more volume through the distribution network.

Don't worry, when this becomes profitable enough(crosses fingers) I will just rent a warehouse or convert a house into office/business space.

Get lost poor bitch troll. Go suck your mom's hermaphrodite cock.

OMG the loser is still posting in my thread even though I IGNORED HIM ALONG TIME AGO.

I can't hear you... since you're blocked/ignored  ::) .... la la lalalla :D

I hope it is profitable enough for you. After a full year of this silliness it is still at the barely paying for itself hobby/enthusiast level for me. The money is to be made around bitcoin, not mining it, in my experience. But, the best of luck to you.

Thank you kindly sir. I will report back here once I've made some progress.
