Hi to all, I'm new to this list and wanted to ask you all for advice on my TiBook 500 Mhz. I would like to upgrade my 20Gb HD that came with it to something closer to 60GB or 80GB. Is this possible and/or affordable? Also, is it an upgrade that can be done by myself (i.e. do I need special tools other than a screwdriver set)? Thanks in advance for all help/advice. Al
