Upgrade iBook

[slooksterPSV]

I'm questioning whether I want to upgrade my internal hard drive or not.
If I decide to do so where can I get this done at? Can I get it done at the Apple Store at the Genius Bar? If so what's the cost? Where else can I get it installed at for the cheapest price without voiding my warranty?

I'm considering a 120GB HDD btw otherwise an 80GB

It will void your warranty and only a 3rd party will do it for you, or yourself.

I've done it to mine when I had my iBook, I popped in a 80GB HD, took me 40 minutes, but you have to be careful.
