BFL time delivery chart is going down, and I got mine today Option 1: (Easiness 9/10)(convenient 9/10)(Power 9.5/10)(Money:4/10)
And BFL is the best to go, I just got one and for only $599 it yields 832 Mhash/80 Watts.
With $10,000 pick up 14 of these super units.
They are very small like 1/5 of a video card I have one
and it runs really well. Plug them all into one computer, and done!
This would yield you 11648 MHASHOption 2: (Easiness 3/10)(convenient 1/10)(Power 3/10)(Money:10/10)
Though the complete best for pure money making will require risers + PSUS + 5830s, rewiring of your house,
using heaters splitting the wires you can get 3000 Watts from heaters.
At least for some.
If done right you can yeild over 30 Giga hashes.
Which I am getting 2.4 Ghash trade of 5830s in exchange for my Single BFL unit.
And plan on trading my other 4 which I can yeild over 11 giga hashes for as little as $2500.
Though the option one that I suggest is the easiest.
