Has anyone built their own HTPC? I built one earlier this year. It is a dedicated 3GHz P4 with 1.3TB of disk storage. The monitor is a 50inch widescreen DLP connected to a high end graphics card using a DVI cable. I use Haupauge PVR 250 tuner cards and have BeyondTV from Snapstream as the main software. Audio output is through a digital connection to an ONKYO 6.1 surround sound system. Remote control is via an RF remote from Snapstream called Firefly. Features, and program schedules look and feel a lot like TIVO, except that the program guide is free and provdied by Snapstream. I record all shows at the best DVD quality which is about 3.3GB per hour. And I can store around 350 hours of DVD quality TV. The system has been operating 24x7 for the past 3 months without any serious problems.
