Should I upgrade an old MacBook (2,1) to Mavericks? I have this old machine:

  Model Name:MacBook
  Model Identifier:MacBook2,1
  Processor Name:Intel Core 2 Duo
  Processor Speed:2.16 GHz
  Number Of Processors:1
  Total Number Of Cores:2
  L2 Cache:4 MB
  Memory:3 GB
  Bus Speed:667 MHz


I've read that Mavericks is good for old machines ... but is this too old?
It's currently running 10.5.8.
Sorry ... according to http://www.apple.com/osx/specs/ it's not even possible!
