I have noticed some specks of dust between the actual screen and the glass panel on my 4 day old iMac. I called Apple (don't have the AppleCare plan) and asked them if my warranty would be voided if I were to remove just the glass panel. They said it would. They told me that I could bring it into an Apple store or to a certified Apple reseller/repair shop. However, I don't want to lug around my computer so I was wondering: will it actually void my warranty if I were to remove the glass panel in order to get the dust out? Also, how would Apple know if I removed the glass panel?
