My dual Opteron 6180 machine does 100k-120k per day on Linux for reference. Guess that would be 14k-17k Boinc ppd. Uses 400w doing it though. I don't mind the power draw so much in the wintertime as it makes for a mini room heater.

Bought all the parts used and put together the system. $100-200 each for the CPU's.

I might have to put a little crimp in production for a while. Thursday night, I went to bed early and just as I was getting to sleep, my wonderful Better Half came and said she had turned up the thermostat because the house was getting chilly. Nothing happened. So I got up and dressed and went to check the furnace. The blower motor that helps to expel the exhaust gases was red hot and not functioning - bound up.
We had installed this furnace when natural gas came to our area about 16 years ago. We replaced an old oil burning furnace. The new natural gas furnace was one of the 90+ efficient models and certainly saved more than its cost in fuel over the years. It cost about $2000.00 at the time. Never gave us a hint of trouble in all those years.
Needless to say, I had to call out a service tech in the middle of the night to see if we could get the furnace running. Once he got here and did a little investigation, it turns out the furnace itself was shot. Not only would it have cost about $800 to replace the part which failed, but the heat exchanger had cracks in all three of the chambers. This meant the furnace was a carbon monoxide accident in the making. I do have carbon monoxide detectors but they never triggered, but it would only have been a matter of time, possibly a short time before they would have. So it turns out the part failing was a blessing in disguise.
After finding this out, I discussed with the service tech the options for a new furnace. Much to my chagrin it turns out they have gone up in price somewhat since we got the last one. (Not like computer power.) So, for a little over $5000 a replacement could be purchased and installed the next morning. So the next day a new furnace was installed. It took from about 9:00 in the morning to after 7:00 at night to complete the installation.
So now I have a shiny new furnace, a warm house and a hole in my wallet, but at least we now have safe heat.
Stay safe everyone.
Cheers

Very lucky nothing happened to your family. No warranty left on old furnace? They are not cheap, thats for sure. We have our inspected ever couple years to insure nothing like this happens. Wallet may hurt but you can sleep safe now, which is what counts.

So glad you're safe. What a scary event, and so lucky your wife noticed. But it would take a bite out of the bank account.
