Actually ... I forgot ... strictly talking 12G, there are none that support 2003.   Dell is still selling some 11G servers that support 2003 (R310's and R415's (AMD)) ... but the R410 is no longer available on their site (was a week or two ago).   There is very little that cannot be done on a VM ... I would research whether or not your software/hardware must have direct access to the hardware ... VM may be the only way you can get it running on a 12G server ... or get an 11G server.
We have a project that requires 1U-sized servers with sound cards and software that requires Windows XP 32-bit.   Has anyone successfully installed XP on any of the current generation Dell servers?  Yes, i know Dell no longer supports XP at all but i'm sure someone out there has at least attempted what i am trying to accomplish.
Anyone with a successful installation of Windows XP on any 12th-gen server?
