Im trying to cut any costs out of my new computer system and Im definitely not afraid to open the case up and install new components. My question is this - should I get a HD installed in my new computer or can I re-use the 20 GB drive I currently use? I have a Pentium III 600 Mhz with Win 98. I've heard that you can experience "conflicts" by installing an old HD as a "new" primary drive. Is this true? Should I just shell out the $100 or so for a new HD? Thanks in advance!
