A cascading failure is a failure of interconnected parts in which the failure of a single part can trigger the failure of successive parts. Such a failure may happen in many types of systems, including power transmission (you may recall reading in the news that many early blackouts were caused by a power cascade from a single blown transformer), computers, home heating and cooling... any system of multiple parts could suffer a cascade failure.
Was there an unprotected power surge that destroyed the machine? I find it unusual that Apple wouldn't make an allowances for a machine as near to still having a warranty as you state. Have you tried escalating the claim with Apple?
If you had a home power issue your homeowners insurance may cover part of your repair.
I had a cascade failure of my home heating and cooling systems this spring due to a nearby lightening strike in a thunderstorm. No other appliances were damaged but apparently the wet grass allowed current to enter the outdoor AC unit, blow up it, the furnace and the thermostat... without causing any bangs, fires or smell of burning materials.
The first clue I had that anything was wrong occurred two days after the storm when I went to turn on my AC and nothing happed.
If this answer is acceptable please remember to return and mark it.

What ended up happening with this? I currently have my Mid 2011 27" iMac in with the Genius Par and they're quoting almost $1,000 in repairs for first, the power supply. Now that they replaced the power supply, they're also now saying the Logic Board needs to be replaced. I'm afraid of a cascading issue, also. I had taken it in earlier last year because the screen was going black and they let me know of the replacement program, but they said there was nothing wrong with my video card.
Just wondering if you were able to get anywhere or if you did the repair. I'm trying to talk to Apple about it now before I decide on what to do.
Only option they gave me was pay the $1000+ for parts and labor or "invest" on a new imac. Honestly I didnt have the money to do either and my imac has been collecting dust in my closet. At this point is it worth it to repair or even selling it for parts? I even looked on ebay and there was one for sale with the EXACT same problem.
