First thing I would do, is build a 24X36 room to house it all in. I would pick up two Barco Graphics 1209 9" CRT Projectors. Screen would be a 144" perf screen to mount the center behind it. During construction, I would run the wire for 11 speakers, three up front, two speakers per surround. Those speakers would be either M&K THX Ultra, or Paradigm Reference. Subs would be replaced with SVS 16-46 PCi subs.
Since Money is no object in this dream, I would pick up an Anthem Statement, or Macintosh pre with Mac or Krell monoblock amps for each speaker. Depending on the room, I would have 9, 12, or 16 reclining love seats for seating. Toshiba HDA-1 for source, along with my HTPC and HD DTivo. I would find an ATSC Modulator to convert my HD DTivo to channel 14.1 and pipe it into my HTPC via an ATSC tuner card. It might me cheeper to find a comp. vid in card for my HTPC tho. I would use my HDDVDR/RW to burn my HD Content to dics for archival purposes.
I know I am forgetting something, so I will update when I remember
