And there is a lot more to opening the drive than removing a few screws.
I'm mystified why you disagreed with my earlier suggestion about getting an Apple certified refurb with a 3 year Applecare agreement.
that users can't do much about contaminants being drawn into the drive
A: Ive cracked up quite a lot of superdrives, there are tiny screws around the casing, and the sheet metal itself has indent snaps holding the top and bottom together; its a bit of a pain to pry one open. I know exactly what Im doing on the superdrive. Its a $40 superdrive, not the processor, winks 😉
(again do not recommend any everyday user do this)
You can see a Qtip being used on same here:

Though the guy is using benzine I dont recommend, the better way is a slightly damp one (water),.. then a dry one,.. then a third dry one.
As any optician will tell you, you want to remove dust/ debris gently BEFORE wiping it down with a dry (anything). Using a dry wipe of any kind on a dirty lens drags debris across the lens scratching it AND the coating. (same reason you should rinse your glasses if dirty before wiping them off).
Contrary to what some people feel, the Panasonic made superdrive (formerly made by Hitachi) is a very robust and well made slot loading burner/player, but its rather mechanical and prone to dust and fuzz, and misuse etc.
B: I personally dont buy or worry about 'certified' refurb, I used to fix computers and I know how to eyeball them in purchase, and can fix anything myself, and as for insurance: There is a much cheaper option, its a TYPE of insurance called "inland marine insurance" $40 a year roughly gets 0$ deductible, against theft, accident, spill, any damage at all, even on a desktop unit that just dies out of the blue. Perfect for portable notebooks http://en.wikipedia.org/wiki/Inland_marine_insurance
been using that TYPE of insurance for 20 years almost.
yes, a certified refurb is a good option for the everyday user.
C: "contaminants being drawn into the drive".... Actually you can do something about this, in removing the superdrive (just myself), I have taped all around the two halves of the superdrive where the top and bottom joints meet to make a seal from air being drawn thru the superdrive chassis itself.

iMacs arn't designed for the US Millitary or the EU
I did not mention any such thing about the Imac...., rather long term OPTICAL storage has had endless millions dropped into same by the EU, Military, and governments. 😊
