[Ben Heckendorn] put together this little beauty on engadget. It’s not quite as over the top as the XBox 360 laptop, but there’s a reason for that. He’ll be putting up a How-To series covering the construction. If you’ve been pondering building a portable yourself, it’ll be a nice jump start for your hardware hacking skill-base.
If you glanced at the PS3 and thought it was too expensive, this might help you justify spending your green. [ken_vs_ryu] put up a mini tutorial on running mythtv under Linux on the PS3 with an external USB capture device. When you consider the cost of a decent machine, video card and blue-ray drive, it’s not a bad deal. (I’m not sure how many Plextor ConvertX encoders you can run at once.) To get things working, you’ll have to thumb through the Gentoo Wiki for the details on setting up the ConvertX.
