I am looking at getting an Airport Extreme, hooking it up to an external hard drive, and using this as my Time Machine drive. I understand that this is not officially supported by Apple. I am not interested in using a Time Capsule, because of numerous reports of overheating and malfunctions. Could anyone who has an AE successfully linked to an external HD as a Time Machine drive please tell me how they did it, and how stable they think the hack is. Thanks.
