You're review said that:

"You can access the system’s motherboard via a hinged metal access panel, which lifts up and is held into place by a small (very flimsy, so be careful you don’t break it) plastic clip. The access panel itself holds the server’s fan, as well as the unit’s 640Gb Western Digital Caviar Blue hard drive (WD6400AAKS). The Caviar is WD’s standard desktop drive – no low power green drives here, bud."

I don't understand the point of that last sentence. Is it a good thing that this is a blue drive instead of a green drive, or is it a bad thing? Why wouldn't I want a green drive, which has a small energy footprint? (I was actually surprised to see a blue drive in there when I popped open the case.)
