valid points.

i didn't think about that. 

fwiw, i know i'll get pounded for this on the board
but i'm thinking about using two SEPARATE ONBOARD
controllers for my SW raid.  i'm not sure how much
perf boost i'm going to get from the dedicated raid
card at this point (that was pretty much discussed in
a recent thread so i don't really want to start that
debate here).  my rationale is that if the hw card
fails, even if it has multiple ports, i'm screwed. 
using two separate onboard controllers gives me the
cheaper availability i need for now.

yeah.. forking those apache processes seems to be the
perf killer. i'm looking to beef up the RAM if i can
get the system cost down in other areas.
