It's no secret that, if you have a new projection display (front or rear), you'll eventually need to replace its light source. Take one look at them, and you'll see that these aren't your ordinary 100-watt bulbs—that, and the fact that these light sources cost hundreds of dollars each.
In my GearWorks column in our January 2005 issue, I talked about how, depending on your viewing distance, the resolution of your display may not matter. To sum up, your eye has a finite resolution (like a digital camera), and, as objects get smaller with distance, there is a point where your eye can no longer distinguish between bigger and smaller pixels. Over long distances, this is obvious, but it surprised a lot of people that it could be so noticeable in shorter (in-room) distances.
I like to think of myself as a do-it-yourself kind of guy. I'd like to think of myself this way, but, in reality, this is not the case. I don't change my own oil (you want me to go under where?), I'm on a first-name basis with my mechanic (honestly, what Ford owner isn't?), and I call my landlord when the kitchen sink leaks (hey, that's why I pay rent). The two things I do myself are haircuts (thank you, King C. Gillette) and computers (sorry, no funny joke). I've been fascinated with computers since my parents bought me an Apple IIc in the mid-1980s. Since then, I've been modifying and building my own. A few months ago, some part of my brain came up with the idea to build a home theater PC from scratch—and make it silent. Keep in mind that this was the same part of my brain that thought it would be a tremendous idea to build a 13-foot-long subwoofer. Thanks to the deluge of e-mails I received after that piece (one—thanks, Mom) and the difficulty in finding a company that makes an HTPC (last count at CES, there were only 13,002 or so), I figured I'd design and build Home Theater's HTPC, the ugliest and quietest ever.
