My personal opinion, I could care less if a psu looks as ugly as sin, as long as it does it`s job very well and doesn`t bring my pants down over the price. If it looks hurrendously hideous, it can be facelifted for eff sake.
"Dual" is the buzz word in marketing/pcs atm. It`ll be "quad" soon enough.
Agree with the other guyz, it`s either fanless or not - lots of psus either act to load, or can be told to act to load.
