At least we have an FAQ on this:
<H3><A name="3.7">3.7</A>) What computer hardware should I use?</H3>
<P>Because PC hardware is mostly compatible, people tend to believe that
all PC hardware is of equal quality. It is not. ECC RAM, SCSI, and
quality motherboards are more reliable and have better performance than
less expensive hardware. PostgreSQL will run on almost any hardware,
but if reliability and performance are important it is wise to
research your hardware options thoroughly. Our email lists can be used
to discuss hardware options and tradeoffs.</P>
