As to cost, you cannot be drawing more than the wattage of your

hard drives and peripherals drawing power.

200 Watts X 24 hours = 4.8 KW-HR X cost per kw-hr

Most new psu's are 75% efficient at best, older ones even worse, so a 200W
psu, under full load, draws about 250W. I do agree that consumption at
full
load with only 1 hd and a low power gpu is probably around half or just
over
half of the stated consumption.

Agreed. Your power numbers are for an 80% efficiency factor, BTW.
