I see that early on in the build you painted the PSU's cooling fan white. Was the paint job successful? I have attempted on three occasions to paint fans and every single time they ended up in the trash because of how easily they get out of balance. I've tried both spray paint for plastic as well as high end automotive paint shot through my HVLP detail spray gun. And I'm no hack when it comes to painting either.

I had less vibration after using my HVLP gun, so I'm guessing that even though I've got it dialed way back, i'm still laying down too much paint per coat. Perhaps i just need a smaller needle for my HVLP gun.
