True... if you're not gaming, a fanless Radeon 9000 would sure be nice, too!
And if you ARE gaming, the Radeon 9600 runs nice and cool! There are some without fans, just heatsinks - or you could mod it yourself. Lots of 9600 Pro owners are simply unplugging the fans and running at stock speed or a touch slower. By far the fastest FANLESS solution you can get!
But there's no 9600 AIW... you'd need a seperate TV card which I still think is a good idea, even in a HTPC.
Even if you're not gaming, in which case a TV card + onboard video (if TV is decent) or a cheap PCI or AGP card would do.
Here's another thing... in a HTPC like the ASUS Pundit, you don't get an AGP slot, only 2x PCI.
In such case, the Radeon AIW VE PCI is a super, super deal. It has the awesome TV quality, great TV tuner, PCI, and some half-way decent gaming capability.
Did I mention the awesome visual quality?

Maybe not for Doom3, but for movies, DVD and TV it's touch to beat - especially for that price!
