Hello Linus media group ,
my name is James , I am a certified Apple Technician in Spain.First of all to clarify , I don´t believe this is fair for you , regardless of the origin of the damage. For the components that you mentioned that are damaged ( LCD , MLB and PSU) you would have to get replacement parts , but with a catch , the screen if it´s only shattered would be at a standard cost , but if the logic board and power supply have been tampered by non authorized party , the price of the part is increased. This is known as STOCK price.
I would suggest speaking with any authorized service provider / Apple premium service to get this sorted and make sure to speak with a technician and mention the stock price for the parts. Another option is to call AppleCare and mention the full story and try to make an exception (Known as a CS Code)
As I mentioned , I am in Spain and hard to do anything from that distance , but if you provide your iMac serial number I will check all that I can do for you guys.
For any information or questions please contact me at james_ibz@hotmail.com
Kind regards ,
James Brooks
