The 5400 uses standard EIDE hard drives. Any IDE/PATA hard drive smaller than 128 GB will work fine. Drives larger than 128 GB will work as well, but you won't be able to see the entire hard drive because the 5400 doesn't know what to do with that much hard drive space.
So, if you have any hard drives hanging around from Mac or PC upgrades you've performed in the past, any of them should work fine with your 5400. I think you'll have to set the drive jumper to "master", though.
Do you need guidance in accessing the internal hard drive of your Mac? It's pretty simple: Undo the two screws on the back of the Mac near the ports, unlatch the back cover on the bottom edge, and pull away the cover. The hard drive is on a little plastic sled at the bottom of the computer. Disconnect the power and IDE cables, and press up on the plastic tab that latches the sled in place while pulling toward you to remove the drive sled.
Peace,
Drew
