Powerbook External Hard Drives?, has to work with pro tools though Options

[slowintrepid]

(first off I know there is a similar post right below me)

anyways. I have a powerbook G4 and I'm gonna be running pro tools LE with an M-Box and maybe logic. my school recomends that I get an external firewire hard drive with 7200 RPM"s as the minimum. I also know that pro tools is pick about what hard drives you use.

my question is. either what external hard drive is good for my set up.

and 2. is it possible for me to take a internal HDD put it in a case and and use it. (I know it's possible but would it work for Pro Tools)

and finally if I was to go there external/internal route. How to I hook up the drive to my comp??? does the case come with a firewire output or something??
