Type of hard drive

[Fran Mack]

I want to know the brand and type of hard drive in my cube. I checked system
profile but couldn't find the information. Where should I look? I'm thinking
about an upgrade and I want to have an idea of what I'm looking for. I want
to buy what I need but don't want to spend more money than necessary. Also,
I don't want to have problems due to my ignorance. Suggestions would be
appreciated.
TIA,
Francine
