Was the computer a whitebox system or a system from Dell, HP etc?
Im guessing, that if it was a propriety system (from Dell or other), that you cannot claim replacement of "other" parts that you have included into the system yourself. Essentially you have broken their warranty agreement by opening the case. If it were a whitebox vendor, then you may have a chance. If you built the system yourself, you can only try with the supplier.
As a business owner I would question you on the procedure you performed to add in the parts and many other surroundings. I would maybe offer you a service to recover data, but would charge you.
It becomes a very hard issue to prove or disprove that your parts didn't cause the shortage.
I'm from Australia, where our laws are pretty close. You then have to contend with, questions such as , was your system plugged into a surge protector, what is the power like in your house. Im pretty sure proprietary vendors will state in their fine print that your should use surge protectors etc.
Very hard question to answer. In the short term I would say NO. No replacements, no data recovery. They may offer replacement of power supply and original components. To use an anaolgy, if you put a turbo on a car and engine blew because its water system wasnt up to speed, who do you blame.
