Install Osx on internal mac drive that is in an external usb case

Hi,

I am looking to install OS X on my old macbook pro hard drive that is in a usb hard drive converter case.

History - A while back I personally replaced my hard drive because my old one had a corrupt install on and I

wanted to upgrade, but there is now an unrelated problem with my Mac Book's logic board that is apparently

covered by apple whether it is in or out of warranty because of a defect in the GPU (Black screen of death issue!

http://support.apple.com/kb/TS2377?viewlocale=en_US ) As my mac was out of warranty I didn't think twice when I

recently upgraded my hard drive myself, now I am a little anxious as I believe Apple will use this to void their

promise to replace the logic board in OR out of warranty beacuse I replaced the drive myself.

For this reason I think it is best that I restore the corrupt hard drive and then replace it in the mac before I

return it to Apple, is this the right thing to do?

The logistics of doing this are a little complicated as I don't have a screen (or the option to use extertnal

screen) on the macbook due to the gpu issue so cannot simply put the hard drive back in and reinstall while in the mac.

I am looking at the option to format my old drive and then install osx on it in the external caddy case. Is this sensible/easy to do?

I cannot afford a new laptop or to pay for the repair so I am desparately trying to get it fixed by apple.

Any advice on either issue would be amazing!!

 

Hi

I have a g5 not sure if the hard drive will fit into that?
