Cost of used Sun Enterprise 420R quad-processor rackmount server: $150 plus shipping (you guys still rock – that’s an awesome Christmas present!)
Cost of electricity to run said server for one year: $793.22.
For contrast, dustpuppy uses $385.60 worth of electricity per year. It just so happens that at the moment, I can calculate it to be slightly larger than $1 per watt for one year – dustpuppy uses 350W and HomelyGosling uses 720W. Math:
8736 hours in a year x .720kW x $0.12611 per kWh = $793.22
I’ve got to start adding an energy surcharge onto my $0.00 hosting fees. 🙂
