These (we've seen others recently on the forums) appear to be a special make-up for some company and are not standard Dell servers.  They appear to be similar to Dell's "cloud" servers, but they are also not entirely the same either.  Your best bet would be to go directly to Intel (5000-series chipset most likely), Aspeed (onboard graphics), Broadcom (NIC's, possibly), etc. for drivers.  You could also try drivers from the download pages for the "cloud" server models if thinking about installing a newer OS, as Server 2003 is not officially supported for their cloud servers (2008 R2 only).
After searching the Dell support site I can find no documentation on this machine.  Would appreciate any info relating to drivers, especially those that might pertain to a Windows 2003 server install.
