[G4] Seagate hard drive Installation

[Pat Smith]

I'm reasonably proficient with tools, but I've never installed a hard  
drive.   I want to install  a 500 gb Seagate hard drive
(  http://eshop.macsales.com/item/Seagate/ST3500630A/  ) in my G4.

My G4 is as follows:

                 Memory                    065-3707  2.0GB PC2700 DDR

                 Hard Drive                065-4144  2X180GB Ultra

                 BlueTooth                 065-4143  BlueTooth
                 Airport                   065-1899  None
                 Keyboard Language         065-4094  Apple Pro Keyboard
                 Mac OS Language           065-4069  Mac OS

                 Country Kit               065-4068  Country Kit

I have the manual that came with the G4 that shows how to install a  
hard drive.

QUESTION:   Is this a plug-and-play project, or should I take my Mac  
to Apple and have them install it?
