Thanks all. I had a lot of fun planning and setting it up. It is not as bad as one might think. I think I mentioned before I have a good friend whose son is an electrician. I got a chance to talk to him about my setup at his dad's 65th birthday party. He pointed out quite a few things I could do to reduce the watts used. Little things like heavy gauge power cables (12 gauge) where lighter gauge (16) would have less resistance and serve just as well. Too fast fan speeds that do not allow the air to pick up heat before being exhausted from the case and using more watts. The big one was properly loading the PSU's to ~80% of capacity rather than having more PSU's running at 30-40% capacity. This causes some of the excess potential being burned off as heat rather than doing work (I use the term work in the Physics definition of the term). This allowed me to reduce the total number of PSU's in my configuration.
Doing all this allowed me to add ~1,000 more watts with only a small increase in watts used. These numbers are preliminary and I am still using a lot of electricity but that's OK for now.
Replacing the MNB-MAT 4715KL-04W-B56 fans with high-volume, low-noise Arctic fans has greatly reduced the noise level.
So far so good. I wish I could run CPU's, GPU's and miners but then my bill would be >$1,500/month and that is not acceptable. I will have to shut down the miners in May and go back to normal CPU/GPU crunching.
Thanks again for the support mates.
