The only parts considered user-accessible by Apple (for warranty matters) is the RAM and the battery. Of course, if you do damage your computer hardware while replacing or working with one of these components they'll just file it under "accidental damage" and tell you the warranty doesn't cover it.
That said, if you're determined (and possibly foolhardy) enough any part is technically "user-accessible". You'll find many, many threads on this forum regarding the MBP's hard drive being user-replaceable or not.

Ok, the RAM is clear. Apple.no (norway) takes 6070 NOK for the additional 2gb ram on the MBP. That's 1000$. I find that rather sick.
