Condensation concerns, cold weather issues!

@Wilfred,

I suppose it is a matter of how much hashing power and what your costs are. At the moment, the setup generates on the order of approximately 250Euros/Month. Electricity costs some 70 Euros / Month.
I estimate the revenue will drop 10 - 15 / month until it will no longer be profitable (ie cost = revenue) at which point, either I will have to increase hashing power or stop mining.

Now, if the price of BTC rises, then it becomes more profitable in the short run, or I can go on longer. If the price of BTC drops, it may end up being unprofitable tomorrow. Don't really know. I am hoping to manage this way until I recoup costs (10 - 12 months).

Now, I am looking to develop my own boards with some hashing CPUs, however, I don't know much about CPU logic. Some manufacturers do provide some schematics after you sign an NDA agreement, but I hate that I have to buy a bunch of chips just to get started.

Maybe someone on the forum has some experience in building a hashing unit from scratch (using existing ASICS).
