Have anyone had a problem with sata card with Apple Power Mac G4?

My 17 yr old daughter has the Power Mac G4 dual 500Mhz model. I upgraded the hard drive and RAM, as well as put in a more capable video card and she's been happy with it. Sure it's older and can't be upgraded past Tiger, but it's a very stable system and perfect until she outgrows it and needs something more powerful.
