I want to add the card to add a new 250 gig hard drive instead of my current 120 gig primary hard drive. This is the smallest hard drive I've got. Can you point me to site that might have pics and/or video of how to do this? Also, I'll take recommendations on brand and/or where to buy the card if you've had a good experience with one. I've got a G4 1.25mhz mirror door with OS X 10.3.9 and 1.25 of ram. Thanks. Ron in Memphis
