According to the technical reference guide for the Deskpro EX (ftp://ftp.compaq.com/pub/supportinformation/techpubs/technical_reference_guides/137h-0800a-wwen.pdf), this model uses the original Intel 815 chipset which does not support ATA100.

So don't buy the hard drive unless you also purcahse an extra IDE hard drive controller.
