Thanks to several people, Alan Rollow, Martin Anderson, Aru Arunasalam,
and Benjamin Ingwersen I was able to deduce.
The ds20 uses a switched type motherboard where the ds20e uses a bus.
The DS20 as well only comes in a small desk side pedestal form factor
where the ds20e comes in both. The ds20 supports 2 ev6 500mhz cpus where
the ds20e supports the 500 as well as the ev7 667 and ev8 833 cpus. Thus
the ds20e can support 4 and 8 mb cache per cpu (depending on the cpu)
and the ds20 only supports 4mb. I have been told the ds20 can support
the ev7 cpus but I wouldn't try that myself. Both computer support up to
4gb of ecc sdram memory. There were some differences in scsi controllers
but that isn't worth mentioning. Compaq still sells the ds20e new as
well.
Thanks for everyone's responses.

Managers,
We are looking to purchase a ds20/e but we are not versed with the exact
hardware differences between the two. Can anyone enlighten me on the
major differences between the 2 computers?
TIA
