If you want to use Time Capsule for Time Machine? Or will you use it as a network drive? Or maybe you're just looking for a hard wired Time Machine? You can get the same function of the AEBS and a regular USB hard drive for Time Machine wireless or network drive. Or there are different solutions for different needs.
