I've turned off 4 PS3s because of the rise of electricity costs and the heat of the summer.
The dedicated big A/C unit in the computer room won't need to run as hard now to keep the Servers cooled down either.
Not sure I'll be bringing them back online this winter, as I'm sure I have some nephews and nieces that might want one for gaming (gasp)...
OGR is almost done now anyways.

PS: If anyone in the USA would like a PS3, make me a reasonable offer. I have all the original boxes etc. Broke in, ready to go
