I concur; I actually purchased some Barracuda V drives recently, and
they're even quieter.

  |    slower the fans can turn and still get the same amount of air
  |    exchange.  I really like my Antec 1040.  (The OEM name for that
  |    case is Cheiftec Dragon.)

The Antec TruePower power supplies are very good too.

  | 4) the cpu fan needs to be replaced with something quiet.  I put a
  |    normal 80mm case fan on a 80mm to 60mm adaptor and used that
  |    instead of the AMD OEM fan on the Athlon.  This allowed me to
  |    substitute a slower turning fan for the high-speed whiner that AMD
  |    gives you with the boxed Athlons.  Warning: Newer Athons put out up
  |    to 80 watts.  Mine was being an older model (1.1Ghz) only puts out
  |    40 watts.  You may need to get a much larger heatsink before you
  |    can put a slower/quieter fan on it.

For this I can recommend the Zalman "flower" coolers:

*Very* quiet, and keep the CPU very cool too.  (I had a XP1600+ CPU,
and I recently installed a XP2500+ "barton", and they both run cool
with the Zalman).
