NeoDude,
you will have all the fluffy ones banging on your door, think of global warming and your carbon footprint.
If they want to do away with a standby mode on electronic equipment they will not take lightly to you leaving your computer on 24/7
Needless to say I leave my file server on 24/7 so I can access it when I am away. When I asembled it I installed a far larger power supply than needed so it would not be overstressed and the cooling system to the server is way over the top to cater for a possible summer heatwave.
