Mattmiller,
The assertion that "Any HI END Server, NEEDS to be connected directly to the router via a cat 5" is not correct. You can have a high performance, hi-end server that includes its own drive (blu-ray or otherwise) for directly burning music to a local drive - no internet connection required. A "streamer," on the other hand, requires a network connection, such as via cat 5 cable or otherwise. (This is an issue that frustrates me to no end, with a number of products out there nowadays that are nothing more than "streamers," with no ability to rip and store their own data, masquerading as "servers").
Psag - echoing djohnson54's comment, what is your server and what are you hoping to accomplish?
