Oh, if you don't solo-mine, and join a pool, you will earn approximately the same on average (0.85% * 25 BTC = 0.21 BTC per month).

<p>If I have 1000 (or more) machines with CPU (and no GPU) solo mining (12 hours/day), will it be profitable?</p>

<p>Forget about the costs of electricity, etc...</p>

<p>I want to know if doing more than 1000 machines solo mining (CPU) will win any bitcoin?</p>

actualy i´m thinking about the possibility. If it is profitable or not.

More than 1000 CPU solo mining = bitcoin?

If those are reasonably decent CPUs, they could be able to mine up to 20 Mhash/s each. Together, that's 20 Ghash/s, or the same as a small ASIC, and using massively more electricity.

As of december 2013, with the difficulty at 707408283, this means that you'd have approximately a 0.85% chance per month to win a block (worth 25 BTC).
