If you think it's a fan causing the vibration you try unplugging them one
at a time until you find the culprit and then replace it. Sometimes the
side panels will vibrate for no apparent reason and by applying finger
pressure around the case when it is humming might enable you to identify
the problem source.

Hi Hobo likewise sorry for delay in responding to you reply, it's not a fan
itself as i have moved fans around, it's the fan "location" that cools my
hard drives that is the problem not the fans themself, i have taken fan that
cools hard drives (and makes the noise, and moved it to bottom of case and
it's fine), as i told ShadowTek i'm going to have a play next week and i'll
let you know how i get on as well.
