[Taggert_LOA]

I'm looking for the quietest of the two. around 500w for the psu and 120mm for the exhaust fan.

 

[Taurus]

power supply:
Coolmax 450w, silver
Coolmax 450w, black

120mm fan:
Vantec 28dBA/53CFM
Antec 30dBA/79CFM
Enermax 25-30dBA/63-95CFM Adjustable

you can shop around and maybe find these cheaper elsewhere.
