Dell makes way too many for us to simply "recommend Dell" -- impossible. There is a Dell that has been favorably reviewed by a reader -- see the main site under Systems. The BIG issue we have with Dell is not whether they are quiet -- but that they simply do not provide ANY noise information at all -- at least not the last time I looked.
So how will you choose? You know they are not ALL quiet, and you don't know HOW quiet. That's one significant advantage of a smaller PC maker like ARM Systems
who are willing to submit samples to us for testing. The big PC makers generally ignore SPCR & hardly even reply to emails.
This continues to be an issue with the big PC makers. Most provide little if any noise info. HP provides dBA power info only on their biz line, which is odd. Evidently, they have the info on their home line & choose not to publish it.
