It won't hurt the other components to get them wet with alcohol or even water if you need to rinse it. Isopropyl alcohol might damage or remove printing from certain types of labels though, so be careful of those.

I'm not sure what the formulation was in the past but denatured alcohol nowadays is just ethanol with maybe 5-10% methanol added. You definitely shouldn't be drinking it (in vivo, methanol is metabolized to formaldehyde via oxidative reduction - formaldehyde attacks the optic nerve - which is why drinking wood methanol makes you go blind) but other than that, I wouldn't say it's particularly more harmful to you, boards or components than isopropanol is. You wouldn't want to drink that, either!

I thought he was joking? I hope nobody would use acetone!

Alexandre, I have such a power supply but have no sense of how much it takes to send to Brazil. I am in the US. Also, this particular supply is noisy but it functions. I think I read that you are only looking for the case, however. Is that right?
