A:AnswerPut one in a dell Expirion 660 Desktop. I think the review that said it will work with all dell desktops is true. Great power rating and all kinds of cable variations make it a good replacement. .
A:AnswerI was able to fit it into a Rosewill FBM-X1 MicroATX case. Being that it is not modular, be ready to work at cable management for any unused cables.
A:AnswerThe only moving part in the power supply is the cooling fan. I have a several power supplies and usually the fan begins to make noise as it gets a few years on it. If you're power supply is making noise I'd return for repair/replacement. But make sure it's the power supply and not video card, DVD/CD or other periphal.
