You might have better luck at alt.sys.pc-clone.dell.
If memory serves, it's basically an ATX mainboard, but with nonstandard
power (separate 3.3V connector), a proprietary front panel connector, etc.
The Dell case was probably made by Palo Alto Products, but I don't get a
response from their web site.
As the XPS 300 dates from 1997, there may not be much point in salvaging
anything from it. Graphics cards are better, hard drives are larger (and
faster), CD drives are faster, etc.
Good luck.
