Running a full-sized desktop computer as a simple backup server is overkill. You don't need a lot of processor power or memory. If all you really want is some extra storage space to use as a backup, then a NAS is the perfect way to go. Even a processor that is used in a cell phone is adequate, and you don't even need 1 GB of memory, either.
