you should do more testing, (then post)
there is no shortage of fanless psus, buy some with the other equipment you plan on using and see how well they handle the load
- and do they too have an objectionable hum ?

I've tried several and they do smell toasty, is odor objectionable ?

once you resolve the psu setup, move to the next phase

talking about this and that all in a jumble is just talk, but hey - thats fun for some too
opinions never substitute for data
