A node can be just a motherboard in a big box called "cluster". It can also 
have its own case, but it will still be just as small. So I'd even say a 
single Xbox takes up as much space as a single regular node. 

The fallacy of such comparison is in that it does not take into account the 
fact that you need _many_ Xboxes to replace one regular node.

Consider a node that is a _dual_ Athlon 4 at 2000+ MHz. To match it with pure 
CPU speed using XBoxes, one will need 6 of them. That's $1000 right there. 
Add the mod chips, labor, network costs, maintenance extras, inability to 
upgrade; and the XBox option just doesn't seem very attractive to me.

OTOH I wouldn't want to stand in the way of innovation, so if you _must_ make 
a Linux cluster out of  Xboxes, good luck!
