Hi all, this is my first post here. Long time DTV subscriber, but never had any issues or considered doing anything other than "watching on my TV". Well a few things have me changing my mind, 1st being all the available apps out there, 2nd being a new baby and wanting to view pics on bigscreen and finally my old PC crapped the bed recently (RIP). So the ancient PC is really what kept me from trying to install MedialShare or Directv2PC and trying to network my DVR's. Now that I'm in the market, I was curious as to what features I should look for in a tower. I know a good video card is essential, and decent speed processor,but would a dual core be needed over say a P4, etc... I was thinking about one of the HP MediaCenter towers. Anything I should stay away from or definitely have? This may not end up being a brand new, store bought unit, so keep that in mind. Thanks alot. Big Daddy D.
