hi there. i'm buying and iMac soon and i'm a bit worried about that thermal paste issue. i know it's been a problem in macbooks since it rises their temperature. i don't know if this only affects to macbooks or if the thermal paste fills every mac. so my question is: could this thermal paste be some kind of dark marketing to make your computer die before its time? if this could be true and iMac are also filled with this paste, could i remove it easily not damaging the computer? thanks!
