hello
i want to ask question about the require hardware components to earn 1BTC per week or even per month 
to mine from home
or i should buy heavy rig like this from Asic
also ask about the internet connection speed that require for mining ??
note that the electricity in my country is very cheap so i can run the hardware 24 x 7
thanks
Yes, if you want to make 1BTC per week or even month then you'll need to buy a fair amount of hardware specifically made for mining.
There are a few different things to consider:
> Total hash rate. This is how fast you will be mining coins. Measured as GH or TH, which stands for either GigaHash/s or TerraHash/s.
> Efficiency: Usually measured as W/GH/s and written as either W/GH or J/GH. This tells you how much power your gear is using. Very old ASICs (from early 2013) might use 10 J/GH, while newer stuff might be as low as 0.65 or so. Basically, you can use this to calculate how much power is going to cost you.
>Noise. You said "home mining." Make sure that you don't buy something that sounds like a jet engine or you might regret buying it.
Look at the different hardware manufacturers and see what you want to buy. Make sure you don't pre-order something, that's a good way to get burned. Subjectively a few of the better hardware vendors currently are:
>Spondoolies: Probably the best, tend to have efficient but expensive and loud miners. The new SP20 is quieter and cheaper, so it might be a good option.
>Bitmain: Also good. Currently not the most efficient, but a reliable option.
>ASICMiner: Probably the cheapest way to get the most hashrate but there have been a few problems with their newest gear. The picture you posted was an ASICMiner Prisma. They can be had for very reasonable prices given the hashrate but know that they are also kind of buggy.
A good strategy would be to see if you can find used hardware cheaper, since BTC mining gear often becomes obsolete long before wearing out. Depending on where it has to be shipped though, that might not get you as much as some people. We recently scored a bunch of Bitmain S1s which we were able to underclock to run at 1.1-1.2 J/GH for just the cost of shipping. That's not great efficiency right now but we also have pretty cheap power.
To answer your question about network bandwidth if you get a miner which supports stratum (anything even close to new) then you could run a few miners even over a dial up modem. Internet bandwidth is not a major concern, but the amount of power you have available might be (depending on how much gear you want to run). If you want 11TH and you get gear that runs at 1 J/GH then you need 11KW, or 50 amps of 220 service just for your miners.
I would also advise that maybe you want to be careful before sinking a ton of money in something you don't have any experience in. That's not to say don't mine- by all means do- Just be careful of how much money you put in relative to what you can afford.
You should probably familiarize yourself with the history of bitcoin and bitcoin prices, and look at how the mining difficulty has been increasing recently to decide if you want to go with more efficient gear or cheaper gear. A couple manufacturers are expecting new chips early next year which might create mining gear in the 0.3 J/GH range. Something like that could substantially increase the difficulty, so plan accordingly.
Good luck and I hope you enjoy mining!
