This is a computer designed to sit in the living room with the rest of your
A/V gear. The idea is that it will record and serve audio and video files for
replay via your existing television and stereo. The current notion is that this
computer should be built in a special case that makes it look more like a stereo
component, the size of which can present a challenge when it comes to getting
all the necessary parts fitted.

For this system a mid-range processor will be fine, along with a generous
amount of RAM. A fast Ethernet connection will facilitate sharing large files.
Youll also want a TV tuner card (or two) to get video in and out of the machine.
Many of these also provide DVR (digital video recorder) functionality, often
without the monthly subscription fees and DRM (digital rights management)
restrictions required by companies like Tivo. A wireless keyboard and mouse
provide for couch-based use and a separate monitor may be unnecessary as your
TV will fill that role.
All components should be as quiet as possible since you’ll likely be watching/
listening in the same room. For this application it makes sense to trade a
little power for passively-cooled (without fans) parts.
