Brandy makes a good point. The only thing I would add is that the 2400 is engineering for a 12.5mm drive. Most of the new ones are 9.5mm. When installing the drive you need to be sure the heat conduction fitting is doing it's job. Some folks have also used thermal paste as long as they are deep in the guts of the 2400. It's not a big deal, but heat is the biggest risk to your 2400. FWIW, I'm running a 2400/G3-320/80MB 9.5mm HD with no issues. Hitachi/IBM Travelstar is a good drive and reasonably cheap at 60-80MB from lots of sources.
