just a note: the 2003 1.25ghz mdd (1mb L3 cache, incorrectly reffered to as 2MB) is noted as achieving a score of 727 on the above chart.
i have acquired one of these machines and just silenced the fans in the psu and u can check its score
on my geekbench account: http://browser.primatelabs.com/user/chrisnova777/geekbench2
(click geekbench2 scores tab) and you will see this machine scores 779 and 780 consistantly when i test it.
