Ummm… Dell…

Dell comes out with new, good looking PC. Good.

Dell says the PC is it's "greenest" PC. Good

Dell says you can add optional bamboo sleeve to the outside of the case.... ummm

Yeah, it does look nice, very nice, in fact. But two things come to mind:

Wouldn't covering a PC in a bamboo sleeve make it run much hotter, making the fan run a lot more, decreasing the "green" aspect of the PC?
Isn't bamboo a limited natural resource? Some poor panda is starving for your PC, not cool, Mr. Dell, not cool.
