So the HD on my parents' late 2006 iMac crashed recently. They're not under any kind of warrantee now. As far as I can see, my options are Have Apple fix it, and probably pay a pretty good amount of money Order one and try and replace it myself (although it's not user-replaceable, so it could get messy) Just buy an external, install the OS, and run from that Option 3 would probably be cheapest and easiest, but I was hoping for some advice on the practicality of that one. Would performance be really bad? Anything else I should keep in mind? I'm really not looking to buy a brand new Mac here. My parents are NOT big enough into computers to blow that kinda money cuz a HD crashed.
