I'm the co-founder of Primal Computing (a performance and speciality PC startup company) that is planning on constructing a home theater PC with all the trimmings (front-panel LCD display, Audigy sound system, dedicated decoders, etc.) in a rack-mount case that is liquid cooled (hence, noiseless). We're hoping to provide this before year's end, so I'll post here when everything's ready.
In the meantime, we're launching a LAN gaming rig in the very near future based on the Shuttle SS-51 case. In the shameless sense of self-promotion,
