@jstew, "no need for a special cord , just take the cord that comoes with the psu and cut the wall end off and get the end for the outlet u are using from the hardware store and put it on the power cable , green to the ground pin , and black and white goto the other 2 pins for 220 as long as ur in the usa. being as u said u have 110 or 220 i take it u are" I'm really hesitant/dare i say afraid, when it comes to electrical things. I don't know if I am competent enough to cut cords and splice them together. Is there an already made cord that I can buy from amazon/ebay or something?
dpends on what wall outlet ur electrician installs , honestly u can wire up a standard 110v outlet to be 220 ( this is what i do , i just paint the ouutlest red so i know they arent 110)
but this isnt up to code i belive , but in doing this u can use the std plug cord without having to change the end.
honestly as long as ur not color blind , replacing the end of the cord is very very simple , infact i can bring home a cord from my data center and take pictures of how to swap the end if u like
if not dust free just be sure to blow the miners out ( with them powered off ) with some compressed air , i clean my miners once every 1-2 weeks
how large is the warehouse and what are the normal temps inside the building?
if its a large area and temps are fairly cool u shouldnt have to worry about extra cooling with only a few machines
now if its a small space then u may have to do something
my miners are in a 3,000 sqft datacenter , and i need no aditional cooling unless ambient air temps are above 85* , in the fall and winter my miners actually heat the building to a comfortable level , infact last year i had issues with my miners being way to cold i.e 14-17*c
also install the miners low to the floor , u dont want them on a shelf 8 ft off the ground as heat rises as we all know
