My gaming PC pulls ~80W at the wall when "idle". Thats about 2 kWh/24 hrs (1920 wH to be exact) if i left it on. At 18c/kWh around here, thats 36c a day, times an average of 30 days..
Thats 10$
Thats not an insignificant amount of money. Its not irrelevant to a lot of people, either.
Im certainly not just going to take 10$ out of my wallet and light it on fire.
With a good SSD, my gaming rig boots up, to a usable desktop, in 14 seconds give or take.
Im usually not even firmly seated before its ready to use.

Mine are all "Something Girl". I think i picked it up from Strongbad cartoons, and it just stuck.
My current one is the "Shifty Girl" because its built into a Phanteks Evolv Shift.
