It's *extremely* important to not repeat incorrect rumors. There are ~ 1,200
DS10Ls in racks of 32 at CPlant, and there are no heat problems. They did
have to add some external fans so that machines that were powered off stay
cool enough to power on, but that's not a significant problem.

Yes, they do. The intent is for the DS10L to faithfully track the DS10 --
they share the same motherboard.
