I've never heard of opening the computer case to terminate a warranty. In fact, even swapping the cards don't terminate it. All these operations are regular maintenance and expected events in the lifetime of a computer. Of course if you botch up and break something, fixing that won't be under warranty.
Sorry, buy I've seen many cases of this where the manufacturers even place holographic stickers on the computers to detect if the case has been opened.
I guess the theory is that while it is under their warranty they don't want you messing with it, but once it has run out then feel free to bugger it up to your heart's content.
