This is pretty neat, but I wonder how much more dense this configuration could be made if one took away the display, keyboard, battery, and chassis of the laptops and just had the motherboard, which (presumably) is fully integrated with a DIMM connector.

If you switch to Mac Mini's and assemble mutiple mini's in a private cloud running VMware, you can have a much more efficient setup. You can do it with xServe's and the latest Mac Pro's as well.
