I'm using a Sparkle 400W, but am looking for another alternative. The Sparkle is way too noisy. The Enermax PS's don't fit in this case properly. I have the 431W that I was going to use. If anyone knows of a good, quiet PS besides the Enermax please let me know.
I didn't use an adapter for the fan plug.
I don't think it would scratch easy. I don't know if it's coated or not, but it feels really smooth.
As far as the noise issue, it's hard to tell with this Sparkle PS in there. I can't hear anything over it. I don't think the fans are producing too much noise though. If I can get this thing quietened down, I will be very happy. Otherwise it's almost perfect.
