I don't know about the HD but the CPU is either 1.25GHz or 1.41GHz

My iBook is 1.25GHz and for normal every day stuff, it flys. Even a small fan would be better than my XP3200 hovercraft sitting in the living room at the moment.

I can see well-heeled people buying several units at a time. It also looks seriously sexy (without trying to sound too sad) Mini-ITX systems that look as cool seem to cost a lot more.
