(FORTUNE Magazine) – Yeah, yeah, I wish all that stuff magically appeared in my house too. But if money were no object, my dream house (all 30,000 square feet of it) would be a full-on geek paradise: video and audio anywhere and a better-than-Hollywood theater, as well as inconspicuous, omnipresent security and computing. So, how much do dreams run these days? The cost of a high-end home installation starts as low as $70,000 and can easily run over $2 million for equipment, programming, and installation.

Here's how I'd build it: First, I'd ditch the TV--even the 42-inch Panasonic plasma model we installed--and buy a projector and screen. We're not talking invite-the-neighbors-and-load-up-the-slides here. The $120,000 Runco VX6-C projector uses digital light projection chips and a blindingly bright 1.2-kilowatt Xenon lamp to present huge, film-quality images. Project it onto the $21,000 Draper RPS Complete/Diamond screen system from the rear, and you can enter The Matrix without hearing the projector fan or worrying about blocking the movie when you grab another bag of popcorn. Wipe the sweat from your brow after witnessing Trinity in all her glory, then flip the switch for the motorized drapes to cover the screen.

But then who wants to simply replicate the theater experience? This is a dream house, not a Loews. So I'd put in three rows of high-end seating and attach--via airplane servos--the motion-simulator system from D-Box for a total of $200,000. The seats (heated, of course) connect through the D-Box to a receiver, allowing sounds to become shakes and movements.

To show off the DVDs, I'd use the $3,500 Lexicon RT10 DVD player hooked up to the company's MC12 processor (for decoding Digital sound) at $10,000. Then, to add astonishing audio, I'd pick up five Krell Master Reference Amplifiers at $60,000 a piece. They are THX-rated (you've experienced THX at the theaters) to provide a speaker blast whenever a Matrix EMP-pulse goes off. Speaking of speakers, my home would have two Wilson Audio X-2 Alexandria units for the front (at $62,500 each), plus $40,000 worth of center and surround speakers, along with a stereo pair of Velodyne's heavyweight Signature 1812 subwoofers for $30,000 a pair. To connect all this equipment, I'd opt for well over $100,000 in Esoteric speaker, signal, and power cabling.

But that's just one room. I want my video and audio in all 30. To get that, I'd buy the monster seven-terabyte audio/video server from AMX (the AMX MMS900), which lists for $60,000 and allows you to rip 900 DVDs or 22,500 CDs and send either audio or video to any of the rooms in the house, all controlled by the Crestron 15-inch ISYS TPS6000 touch panel displays on countertops and bedside tables everywhere.

Crestron's other controllers allow you to not only pick where the music and movies get shown and heard but also to control just about any other part of the house that runs on electricity: surveillance, air conditioning, espresso machine, you name it. Walk through the halls at night, and the Crestron will dim the lighting behind you. Forget to lock your doors--and don't realize it until you land in Taipei? Log on to a web browser and turn the virtual key. A high-end Crestron system like this would cost $400,000--plus another $400,000 for programming and installation.

Total cost: $1.8 million. A geek can dream, can't he?
