OK, I dont see a G4 in the near future, so ill have to use this as my main machine. First, what kind of hard drive do I use? The connectors are this weird kind that I'm not familiar with. It has a weird name, like Ultra2 Wide SCSI or something. Can I use ANY hard drive with it, or does it have to conform? Also, what is the fastest processor upgrade and video card I can get? And Do I need a DVD card to use DVD's in OS X? Thanks!!!!
