I seem to remember a couple of power supplys that would not turn on their fan at low loads, but once the fan turned on it was too loud and would not turn off once the power was reduced, or might turn on and off in an annoying cycle every few minutes.
I can see how that would get annoying actually, sounds like the best option is to have a fanless PSU or or a quiet one like the Nexus. From what you've said eit412 it must be a quiet PSU!
I'm thinking I'll definitely get a low profile graphics card too, by the sounds of it 430w will be fine to power everything.
CA_Steve, I'll have a certainly have a read of that review, many thanks for the link!
Think I'll be able to post a picture of my system after this post
Thanks again everyone!
