No problem Sir..., take your time, appreciate the quick feedback already, I just don't want to take any risk with the basic PDU 9560 because I'll have no way of monitoring my usage in wattage.

And since I'm expanding my operations gradually, smaller home farm going in my former office. I'm still sticking with the 4U case and will be sticking them into the 42U, hopefully I can mount at least 8 4U case in there. All 4U case are fitted with 7 GPU's; the scarcity in GPU's have slowed me down as I'm not going to pay over MSRP for them.

Got all my Ethash Algo build done already with RX570s now trying to pick up a lot of Nvidia cards. For Veteran miners, will anyone of you support 8 1060 4U case build over 7 1070's in the same build. I do understand that with the 1070, they are bulkier and the Rosewill L4500 4U case might not fit 7 of those.

To add, I also like to keep about 3/4 to 1/2 inch space between each GPU in the case to allow room for better air circulation, coupled with the 3700rpm 153cfm Delta fans upfront for intake and 1500rpm 82cfm AeroCool Sharkfin fans right behind the GPUs to help exhaust the all the way back, where I left the 2 80mm fans to help exhaust stale hot air that might hover around the CPU.

Any advice with this setup would be appreciate as I'm not familiar with Nvidia cards but being learning a lot from all Philipma's thread. I'm scared I might not be able to fit up to 20 1070's or more on one 30A breaker, which should be 5760 Watts. Hence why I'm looking at the 1060's as because my goal is to get the best Sols/Wattage per rig.
