iMac G5 HD upgrade

[emptyCup]

I am thinking of buying this Western Digital drive to replace the 80GB drive in my Rev. A iMac G5 (PPC, no iSight). I used to do things like this all the time, but that was many years ago. Now I need some reassurance that this drive will work. Thanks

FWIW, I was considering upgrading my drive but then I thought, how long will I keep this as it's almost 3 years old? I went with an external FW drive.
I felt that the better solution and it would also allow me to take advantage of Time Machine in Leopard.
