You know by now that once Apple announces a new piece of hardware, it's only a matter of time before someone gets their hands on one only to rip it up and tear every little piece out to see what's in there. And that's exactly what iFixit did with the brand new iMac -- most of us would kill to get one and keep it, and they got one and killed it (Update: Apparently they didn't kill it -- they ended up putting it all back together again). But at least we can learn from their destruction: the LCD panel is the same horizontal resolution as the 30" Cinema display, and the screen itself weighs 11 lbs. The hard drive sits right in the center of the machine, right behind the screen. And there's probably more heat dissipation methods in there than you'd expect: six temp sensors, three fans, two heat sinks, and even a partridge in a pear tree. We're not sure how that last one helps.
Overall, it's a beauty. And the last twist is probably the most interesting -- other than showing off your Mac-itude and lighting the area behind your screen, the Apple logo is apparently wrapped with an Airport antenna. Because the whole thing is encased in aluminum, that's the only place to get a signal, and so that's where they stuck it. Now when people complain that you're just being trendy by showing off the Apple logo, you can tell them you're actually just trying to help out the Wi-Fi reception.
