Definitely put your money into the Bridge (why own the PWD if youre not going to get the Bridge). Use your current PC with some interim server software (Twonky works fine) until the forthcoming Tag-N-Play server is released from PS Audio.
Eventually, you can eliminate your PC from the equation altogether - PS will be releasing a router that incorporates their TNP server. Theres no sense in buying a new computer for the Bridge-based music server. In this system, the only purpose of the computer is to run the server software. Basically, the Bridge pulls everything straight from your hard drives (bypassing all of the computers audio processors).
