HD: Seagate Baracuda 7200rpm, reliable and silent.

don't know about the CPU upgrade, thou...

a.

will that go strait into the powermac?

yes, as far as i know you have space for 3 drives in the G4 cabinet, unless you occupied the slots already with other stuff.

just check excactly how old your model is and what kind of connex you need, like sata or ata or ??? just check the excact model, year, speed and ask your dealer.

its a 2002 quicksilver g4 733mhz

i read through the manual, and i think it said ATA drives but i dont know the difference between any of them

Seagate

If you only have one hard drive in your G4 currently, then get a Seagate ST3120026A. 120GB, 8MB buffer, ATA/100, and for less than $100! You will connect this to the other end of the large, thin cable coming from your Macintosh HD. It will mount on top of the Macintosh HD in the hard drive bracket that can be removed from the tower by removing the screw covered by the large, thin cable (that cable is the ATA cable). Take the other electrical connection coming from the same cable powering the Macintosh HD, and plug that into your new hard drive.

The only thing that you must be careful of is to set the Seagate drive you buy to slave mode. There is a sticker on the drive that will indicate what jumper needs to be where to do this.

Good luck!

Check out other World Computing, they should have a variety of CPU upgrades for your model.
