I just got my 27" i5 and everything seems perfect! no yellow screen/bleeding/dead pixels! I couldn't be happier. I got one with a WD HD and was wondering if others with the same HD had the same issue as i do... If it is an issue at all or it this is normal... i'll be sitting in my room (perfectly quiet) and i can hear a spinning noise... very low but sounds like either a fan or the HD spinning. There is no grinding noise just the sound of something spinning... i was wondering if this is normal?
