Hello BeagleBrainz
I have had a look at the operating system, first of all the machine has been partitioned so that it will run Windows XP and Linux EMC2, 2.4.6 using Ubuntu 10.04LTS
As for the Windows side of the unit all I could dig up is the following, Windows XP Version 2002 Service Pack 3 , now it says Windows NT 32, The processor is a AMD Semprom 2200 1.5 GHZ., As for on board RAM I don't have an answer for that and the only reference to memory is 15.9 GB 3.3 used and 12.5 available .
