Another thing a part time sysadmin might not consider is 
applying BIOS updates, if any, for that chassis, and as 
applicable sub-components.  Dell is quite good about issuing 
these, while a unit remains in production, and sometimes 
continues to issue them while it remains in support, 
particularly for the PowerEdge series

I get strange looks from my techs when I insist they do this 
when strange hardware problems are being manifested.  All I 
can say is: 'but this may work'  It worked last week 
with a Tyan motherboard dom0 that was throwing random ram 
errors  :)
